### Example 42: Virtual Spatial Transcriptomics from Archival H&E Slides
**Objective**: Predict transcriptome-wide spatial expression across an archival H&E cohort that was never assayed spatially, and establish — before using it — how much of the predicted signal is biology rather than model prior. Output is model prediction, not measurement.
**Disciplines**: computational pathology · spatial transcriptomics · machine learning · tumour biology · research licensing
**Starting prompt**:
```text
Use the histolab, deepspot-m, anndata, scanpy, pathway-enrichment,
scientific-visualization, and scientific-writing skills. Slides stay in
approved storage. Noncommercial research use only.
Goal: a tiles-by-genes virtual expression map per slide, plus an honest
statement of what it can and cannot support.
Criteria: tiles must be 224x224 RGB at ~0.5 um/px, taken from the pyramid
level nearest that resolution — not resampled from a coarser one. Every
queried symbol must be in model.gene_names.
Deliver: per-slide AnnData with tile coordinates, log1p-CPM values, the
embedding source used, and the gene list; marker maps; a concordance
analysis against something independently known about each slide.
Report: label every value as predicted, never measured. Give the agreement
between at least two embedding sources for the genes you draw conclusions
from, and name the genes where they disagree.
Do not: treat a predicted expression map as a spatial assay result, or use
the model or its outputs commercially.
```
**Skills Used**:
- `histolab` - Grid tiling of whole slide images with coordinates retained
- `deepspot-m` - Virtual spatial transcriptomics from H&E tiles (log1p-CPM, ~19k-gene panel)
- `anndata` - Tiles-by-genes matrix with spatial coordinates in `.obsm`
- `scanpy` - Neighbourhood structure, clustering, and marker analysis on the predicted matrix
- `pathway-enrichment` - Enrichment of spatially coherent gene programmes
- `pathml` - Stain normalization and slide handling for the tiling stage
- `scientific-visualization` - Publication-quality & interactive visualization
- `statistical-analysis` - Patient-level inference on tile-derived quantities
- `scientific-writing` - Evidence-traceable research reports
**Workflow**:
```text
Step 1: Clear the licence and access gates before any compute
- DeepSpot-M code is PolyForm Noncommercial 1.0.0 and the weights are
CC-BY-NC-SA-4.0. Confirm the work — and anything derived from the outputs —
is noncommercial, and check both licences before redistributing a map
- Weights are gated: request access at the model page, then authenticate the
machine once with `huggingface-cli login`
- Record the model version, the embedding source, and the gene panel file that
ships with the weights; the panel defines what can be asked at all
Step 2: Tile the slides at the resolution the model expects
- Use HistoLab to extract a grid of 224x224 RGB tiles, keeping each tile's (x, y)
coordinates — the coordinates are what make the output spatial
- Extract from the pyramid level nearest 0.5 um/px. Resampling a coarser level to
224x224 gives the right array shape and the wrong texture, and the backbone reads
texture; the shape check will pass and the result will be quietly wrong
- Filter background and artefact tiles before inference, not after
- Apply stain normalization consistently across slides, and record which method
Step 3: Fix the gene list up front
- Query `model.gene_names` and intersect it with your genes of interest; an
unknown symbol raises KeyError naming the offending genes
- Resolve aliases to current HGNC symbols before the intersection, and report any
gene you wanted that the panel does not carry
- Keep the ordered gene list beside the output — `predict_genes` returns values
aligned to the list you passed, and an unlabelled column is unusable
Step 4: Run batched inference
- Stack processed tiles into batches and call `predict_genes` once per batch with
the same gene list; concatenate into a tiles-by-genes matrix
- Attach tile coordinates and assemble an AnnData object per slide, with the
embedding source, model version, and units (log1p-CPM) in `.uns`
- Import deepspotm inside the function that needs it and turn ImportError into a
message naming the install, the access request, and the login
Step 5: Repeat under a second embedding source
- The gene router builds projections from one of five frozen embeddings (evo2,
orthrus, prott5, scgpt, apertus), each a different view of gene identity
- Rerun the same tiles under a second source and correlate the two maps per gene.
Genes where the sources disagree are genes the morphology does not constrain;
they are not evidence, and the disagreement is itself a reportable result
Step 6: Establish what the map reproduces that you already knew
- Before any discovery claim, check the predictions against something independent:
an IHC-confirmed region, a pathologist annotation, matched bulk RNA-seq for the
same block, or a marker whose spatial pattern is obvious from morphology
- A model that recovers EPCAM in epithelium and CD3D in a lymphoid aggregate has
earned a little trust for that slide; one that does not has failed a positive
control, and no downstream analysis rescues it
Step 7: Spatial analysis on the predicted matrix
- Build a spatial neighbour graph from tile coordinates and cluster with Scanpy
- Run pathway-enrichment on genes that mark spatially coherent regions
- Do not test the genes that defined a cluster for enrichment in that same cluster
and report a p-value — that is the double-dipping failure with a spatial coat on
- Treat compartment fractions as compositional: one region expanding forces the
others down
Step 8: Get the unit of analysis right for any cohort claim
- Tiles within a slide are heavily correlated, and slides within a patient more so.
Aggregate to the patient before comparing groups, and bootstrap at the patient
level
- Break results down by site, scanner, and stain batch as in Example 11. A model
reading stain signature will produce spatially smooth, entirely artefactual maps
Step 9: Report
- Per-slide virtual expression maps with the gene list, source, and units labelled
- Two-source agreement table and the genes that failed it
- Positive-control results, per-site breakdown, and patient-level intervals
- A limitations section stating plainly that these are predictions from morphology,
that the released panel bounds what could be asked, and that a spatial assay is
the only thing that measures spatial expression
Expected Output:
- One AnnData per slide: tiles x genes, log1p-CPM, coordinates, provenance in .uns
- Marker and region maps with explicit "predicted" labelling
- Cross-source concordance analysis
- Enrichment results for spatially coherent programmes
- Research report bounded to noncommercial use with prediction-vs-measurement
stated in the methods and again in the conclusions

### Example 43: A Custom Carrier That Has to Fit Labware You Did Not Design
**Objective**: Design a fabrication-ready part that mates with a standardized microplate on one face and a vendor imaging stage on the other, verify both interfaces before anything is cut, and hand the geometry to the automation layer as a deck resource. No fabrication or robot motion without explicit trained-operator authorization.
**Disciplines**: mechanical design · laboratory automation · metrology · assay biology · manufacturing process selection
**Starting prompt**:
```text
Use the lab-hardware-cad, uncertainty-and-units, pylabrobot,
protocolsio-integration, scientific-schematics, and scientific-writing skills.
Goal: a temperature-tolerant carrier holding one SLAS-footprint microplate,
bolting to our imaging stage, printable in-house this week.
Data: stage bolt pattern is on the vendor drawing at docs/stage.pdf; I
measured 40.0 mm centres. Plate footprint comes from the standard.
Criteria: every interface dimension must carry its source — a standard ID, a
vendor drawing, or my measurement. Do not write one from memory; if it is not
in the standards database or the family reference, ask me for the drawing.
Deliver: parametric model source, STEP, STL, the manifest, a passing
interface check, and a rendered snapshot I can look at.
Report: the tolerance stack-up for the plate pocket, and what fraction of
conforming plates the pocket accepts.
Do not: send anything to a printer, or move any instrument.
```
**Skills Used**:
- `lab-hardware-cad` - Parametric build123d modelling, standards lookup, interface checking, STEP/STL/DXF export
- `uncertainty-and-units` - Tolerance stack-up and unit discipline across the dimension chain
- `pylabrobot` - Offline deck-layout planning with the new carrier as a resource
- `opentrons-integration` - Reviewed protocol planning where the carrier sits on an OT deck
- `protocolsio-integration` - Recording the assembly and use procedure
- `scientific-schematics` - Assembly and interface drawings for the build package
- `scientific-writing` - Fabrication package documentation
**Workflow**:
```text
Step 1: Route to exactly one device family
- Classify the part and load one family reference — labware adapters here, not
microfluidics, optomechanics, or behaviour rigs. Loading all four mixes
conventions and is a reliable source of error
- Where a part genuinely spans two families, load the family that owns the
critical interface and read only the interface section of the second
- State the routing decision in the response, so the reader knows which
conventions the dimensions follow
Step 2: Write down every interface before writing any geometry
- For each mating interface record three things: the source of the dimension (a
published standard ID, a vendor drawing, or a user measurement), the nominal
value with its tolerance, and the intended clearance with the reason for it
- Look the numbers up: `check.py standards --list`, then
`check.py standards --show slas-microplate-footprint`. Never write an interface
dimension from memory — a guessed interface number is the most expensive
failure this workflow has
- If a number is in neither the standards database nor the family reference, stop
and ask for the drawing or the measurement. "Approximately" is not a dimension
- Size a feature that must receive a standardized component against that
component's maximum material condition — nominal plus its plus-tolerance — and
add clearance to that. A pocket sized from nominal accepts only the smaller half
of conforming plates, which is why this appears in the report
Step 3: Choose the process and material before the geometry
- Read the fabrication-limits reference: process sets minimum wall, minimum
feature, achievable tolerance, autoclavability, and solvent compatibility
- FDM will not hold ±0.05 mm; SLA resin is not safe for cell contact without
post-cure and testing. Pick the process the tolerance budget actually permits,
rather than designing first and discovering the budget afterwards
- Record process, material, and layer height in the model docstring
Step 4: Author the model as parametric source
- The source is the authoritative artifact. Never hand-edit an exported STEP and
never regenerate a model from a mesh
- Every changeable dimension is a module-level named constant with units in the
name, split into an INTERFACE block (fixed by a standard, annotated with its ID)
and a DESIGN block (free choices)
- Derive computed dimensions inside functions, not at module level, so `--param`
overrides actually propagate
- Declare `interfaces()` returning each dimension the part must fit, with its
standard ID and intent. This is what makes step 5 a check rather than an opinion
- Treat model files as executable: `gen.py` imports and runs them. Only run models
authored in this session or supplied from a trusted location, and read any file
from elsewhere before running it — then say that you did
Step 5: Generate, then check the interfaces
- `gen.py` writes the STEP (authoritative), the STL (preview and printing), and a
manifest recording source hash, resolved parameters, declared interfaces, library
versions, and measured bounding box, volume, and validity. Keep the manifest with
the artifact; it is the provenance record
- `check.py facts` must report `is_valid: true`. Broken geometry gets fixed in the
source, not patched downstream
- `check.py interfaces` is the gate on fabrication. Use it rather than `check.py
fit` for anything internal: a pocket, bore, or slot does not appear in the outer
bounding box, so `fit` on a carrier measures the outside of the walls and fails
against the plate footprint for a part that is entirely correct
Step 6: Look at it
- Render a snapshot and inspect it. A numeric pass does not waive this — a model
can satisfy every declared interface and still have the pocket in the wrong face,
a boss where the plate skirt lands, or a wall that closes over a bolt hole
- Check clearance for the plate skirt, lid, and any gripper or pipette approach
Step 7: Close the tolerance argument in units
- Use uncertainty-and-units to stack the chain: plate tolerance, print tolerance,
thermal expansion of the chosen polymer over the assay temperature range, and
the stage bolt-pattern uncertainty
- Report the fraction of conforming plates the pocket accepts, not just a
pass/fail. A part that fits the plate on the bench and jams on 30% of the lot is
a part that has not been checked
- Millimetres throughout, and state it; a mixed-unit dimension chain fails silently
Step 8: Wire the part into the automation layer, offline
- Define the carrier as a resource in a PyLabRobot deck layout and simulate the
moves that touch it — approach heights, gripper clearance, plate seating
- Keep this in offline planning mode. Simulation clearing is not authorization to
move hardware; a physical trial needs a trained operator and explicit approval
Step 9: Build the fabrication package
- STEP as the authoritative artifact, STL for the printer, manifest for provenance,
the model source as the design of record
- Assembly and interface drawings via scientific-schematics, dimensioned to the
same sources named in step 2
- Print orientation, support strategy, post-processing, and the cleaning or
autoclave procedure that the material actually tolerates
- Record the assembly and use procedure with protocolsio-integration as a reviewed
draft; publish only with explicit authorization
Expected Output:
- Parametric model source with INTERFACE/DESIGN separation and an interfaces() contract
- STEP, STL, and manifest, with a passing facts and interfaces check
- Rendered snapshots reviewed visually
- Tolerance stack-up with the accepted-plate fraction stated
- Offline PyLabRobot deck layout including the carrier, with no hardware action taken
- Fabrication package: process, material, orientation, post-processing, drawings

## Preclinical In Vivo Studies & Animal Welfare
### Example 44: Multivariate Severity Scoring and Humane-Endpoint Forecasting
**Objective**: Combine several welfare readouts into one severity score per animal per day, forecast which animals are heading toward a humane endpoint early enough to act, and write the severity-assessment section of a refinement report — without either output becoming a decision rule.
**Disciplines**: laboratory animal science · welfare biology · time-series statistics · physiological signal processing · research ethics and regulatory reporting
**Starting prompt**:
```text
Use the relsa-severity-assessment, experimental-design, statistical-power,
neurokit2, statistical-analysis, scientific-visualization, and
scientific-writing skills.
Goal: one severity score per animal per day across the cohort, plus a
next-day forecast with an interval for the animals still on study.
Data: daily body weight, body temperature, a 0-8 clinical score, an IL-6
readout, and telemetry. This is a sepsis model — temperature falls.
Criteria: state the directionality of every variable and why. Use the
endpoint-reaching group as the reference set and save it, so later cohorts
stay on the same scale. Score only variables measured throughout.
Deliver: per-animal RELSA trajectories with each variable's weight, forecasts
with RMSE, PICP and MPIW together, and KDE zone candidates with a bandwidth
sweep.
Report: the reference-set table, so the scale is auditable. Flag any variable
whose max reached sits on the wrong side of 100 for its declared direction.
Do not: present a zone as a regulatory severity grading, or a forecast as a
euthanasia decision.
```
**Skills Used**:
- `relsa-severity-assessment` - RELSA scoring, ARIMA endpoint forecasting, KDE severity zones
- `experimental-design` - Which readouts, at what frequency, decided before the study runs
- `statistical-power` - Cohort size for the group comparison the severity data is meant to support
- `neurokit2` - Heart rate and HRV features from telemetry, averaged to the scoring interval
- `statsmodels` - ARIMA fitting and diagnostics behind the forecast
- `statistical-analysis` - Group comparison with the animal as the unit of analysis
- `scientific-visualization` - Trajectory, forecast-interval, and density plots
- `scientific-writing` - Severity-assessment and 3Rs/refinement reporting
**Workflow**:
```text
Step 1: Decide the monitoring scheme before the study, not after
- Use experimental-design to fix which readouts are collected, at what frequency,
and for how long — including the baseline window. A variable that appears
mid-study cannot enter a severity score cleanly
- Use statistical-power for the comparison the welfare data is meant to support,
at the level of the animal
- Keep the prospective severity classification required by your authorization
separate from anything computed here; RELSA does not replace it, and the humane
endpoint criteria actually applied to the study are recorded independently
Step 2: Assemble one row per animal per time point
- Columns: id, time, the outcome measures, and optional treatment/condition labels.
The RELSA convention codes the baseline time point as -1
- Derive telemetry features with NeuroKit2 — heart rate, HRV — and average them to
one value per scoring interval, as the published models do. Sum activity rather
than averaging it
- Leave missing measurements empty. They are dropped from the score, never imputed;
a missing value silently treated as "no deviation" biases severity downward,
which is the dangerous direction
Step 3: Make the four decisions that determine the result, explicitly
- Directionality: falling is the default (weight, activity, food intake,
burrowing). Variables that rise under worsening must be declared as turned —
clinical scores, inflammatory biomarkers, fever, tachycardia. Get it wrong and
the variable contributes exactly zero, silently, because deviations the "wrong"
way are floored. Body temperature is model-dependent: it falls in sepsis and
endotoxaemia, rises in fever models, and no property of the data settles it
- Reference set: RELSA is relative by construction and means nothing without one.
Use the group assumed to carry the greatest burden — typically the highest-dose
or endpoint-reaching group. Too mild a reference pushes every score above 1; too
severe compresses everything toward 0. Save it and reuse it for later cohorts
- Zero-baseline ordinal scores: a clinical score of 0 in a healthy animal makes the
ratio undefined. Map the score's scale instead (healthy to 100%, worst possible
to 200%), which also marks it turned — and state that this is a modelling choice
about what one score point is worth against one percent of body weight. The
alternative is to keep the score out of RELSA and use it as an independent
endpoint criterion
- Constant composition: the score averages over whichever variables are available,
so a variable that appears or disappears mid-trajectory moves the score by itself.
Score the variables present throughout, and heed the composition-change warning
Step 4: Compute the scores and audit the scale
- Run the scoring with the declared variables, normalizations, turned list, score
mapping, baseline time, and reference group; save the reference model
- Read the echoed reference table rather than skipping to the scores. For a falling
variable `max reached` should be below 100, for a turned one above it, and
`max delta` should be a plausible magnitude for that measure. A variable that
fails this test has its direction declared backwards
- Keep the per-variable weights alongside each score — they are what makes a score
explainable, and a weight of 1.00 means that variable hit the reference maximum
- Do not normalize something already on a percent scale; that flattens it
Step 5: Forecast the animals still on study
- Fit ARIMA per animal on the trajectory up to the time point before the endpoint
and predict the next score with a 95% interval; use rolling one-step-ahead mode
for live monitoring
- Report RMSE, PICP, and MPIW together, always. A model reaches PICP = 100% by
making the interval so wide it says nothing, and MPIW in RELSA units is what
exposes that — a published row with PICP 100% and MPIW 7.35 covers 735% of the
scale
- Interpolation is on by default because daily sampling is far too sparse for
ARIMA; it buys model selection and narrower intervals at the cost of honest
uncertainty. Turn it off when measurement frequency allows, and state which
- ARIMA assumes stationarity and linearity and therefore cannot predict a cliff:
an abrupt collapse in the last hours will not be forecast from a smooth prior
trajectory. Act on the upper bound of the interval, and never let a low forecast
override an animal that looks unwell
Step 6: Put scores in context with severity zones
- Estimate the score density and take thresholds at its minima — the sparse valleys
between clusters. Include endpoint animals, survivors, and shams; the zones exist
to separate those states, so all of them must be represented
- Check the bandwidth before believing a threshold. On the published sepsis data a
10% larger bandwidth removes both minima entirely. Run the sensitivity sweep and
report the sweep, not a bare pair of numbers
- An empty threshold list is a legitimate result: the scores form one cluster and
there is no data-driven place to cut
Step 7: Compare groups at the right unit of analysis
- The animal is the unit, not the animal-day. Repeated daily scores from one animal
are not independent observations; use a model that accounts for the repeated
measures, and report n as animals
- Report the trajectory shape, not only a peak: an animal peaking at 0.53 on day 3
and recovering to 0.11 by day 7 is a different welfare story from one climbing
monotonically to 1.00, and a single summary statistic erases the difference
Step 8: Report against the checklist
- Outcome measures with units and declared directionality, and why
- Baseline time point or window, and which variables were normalized
- Any ordinal score mapping, with its scale
- The reference set: which animals, which group, how many, and why they are assumed
to carry the greatest burden
- The humane endpoint criteria actually applied in the study, stated separately
- For forecasts: interpolation step, selected ARIMA order per animal, and RMSE,
PICP and MPIW
- For thresholds: bandwidth, number of scores, and the sensitivity sweep
- Software versions, plus the explicit statements that follow
Step 9: State the boundaries in the report itself
- RELSA is an aid to severity assessment, not a decisive parameter. An animal with
a low score that shows other signs of distress is handled accordingly
- Neither procedure is a validated predictor of death
- KDE zones are not regulatory severity gradings; EU Directive 2010/63/EU
categories are assigned prospectively by a different process and the published
work is explicit that its thresholds do not translate to them
- Scores are not comparable across reference sets, models, or laboratories —
always report the reference set with the score
- The published evidence is a proof of concept: 13 animals across seven models,
several rows resting on one or two animals
- An underestimated score is the dangerous error, because it discourages attention
and can delay a decision; an overestimate merely prompts extra care
Expected Output:
- Per-animal RELSA trajectories with per-variable weights and n_vars per time point
- A saved reference model, so later cohorts sit on the same scale
- Endpoint forecasts with intervals, reported with RMSE, PICP and MPIW together
- Candidate attention/danger zones with a bandwidth sensitivity sweep
- Animal-level group comparison with repeated measures handled
- A severity-assessment section for a 3Rs/refinement or welfare report, with the
boundaries above stated in it rather than in a footnote

### Example 45: Checking a Mechanistic Hypothesis Against a Federated Knowledge Graph
**Objective**: Take a mechanism proposed by an internal analysis and establish what a public biomedical knowledge graph does and does not assert about it, with every returned edge traceable to a knowledge source — then verify the parts that matter outside the graph. Nothing proprietary or patient-specific is submitted.
**Disciplines**: knowledge representation · pharmacology · biocuration · evidence appraisal · research information security
**Starting prompt**:
```text
Use the ncats-arax, ontology-term-resolution, primekg, database-lookup,
paper-lookup, scientific-critical-thinking, and scientific-writing skills.
Goal: what the public graph asserts about the drug-gene-disease chain we
proposed, with provenance for each assertion.
Data: the hypothesis is a published-target question and is safe to send to a
public service. Nothing from the internal programme goes into a query.
Criteria: type both nodes with Biolink categories and pin at least one
endpoint. Two-hop queries get exactly one typed, unpinned intermediate.
Deliver: the exact TRAPI payloads, the bounded summaries, a table of edges
with predicate, qualifiers, publications, and knowledge source, and a short
appraisal of which edges are load-bearing.
Report: response order, not rank — the service does not return one. A zero
means "not returned under these constraints", not "no relationship exists".
Do not: run a variant query after an empty result without telling me you are
doing it, or present a returned path as a validated mechanism.

- `networkx` - Local analysis of the retrieved subgraph
- `scientific-writing` - Evidence-traceable write-up

- Queries and caller metadata may be publicly visible even when storage is
declined. Confirm the question is a public, nonsensitive research question
- Nothing patient-specific, no confidential research questions, no unpublished
compound programmes, no proprietary target hypotheses. If the real question is
proprietary, reformulate it as a published-entity question or do not send it
- Acknowledge the public nature of the query explicitly, and choose a new or empty
output directory so artifacts from different queries do not blend
Step 2: Preflight the service without asking a biomedical question
- Verify the endpoint identifies itself as ARAX, exposes /query, and reports a
supported TRAPI version
- A nonproduction endpoint or an untested TRAPI series requires an explicit
override, and no override changes the fixed query shapes or operations
Step 3: Resolve entities to identifiers, as a separate reviewed step
- Use ontology-term-resolution on the free text, then normalize through the client
with the expected Biolink category
- Normalization is review-only and triggers no graph query. Read the canonical
identifier, name, category, and synonym preview, and report every CURIE and
category regardless of what happens next
- A category warning or a zero result is a reason to curate the identifier by hand,
not to chain automatically into a query with a doubtful CURIE
Step 4: Ask the one-hop question with both nodes typed
- Pin at least one endpoint, give both nodes Biolink categories, and state the
predicate. Add qualifiers where the direction of effect is the point —
activity_or_abundance decreased is a different claim from increased, and an
unqualified predicate collapses them
- Default lookup mode fixes expansion to RTX-KG2 and returns 20 results; the hard
cap is 50 in either mode
Step 5: Ask the two-hop question with both endpoints pinned
- Exactly one typed, unpinned intermediate node — this is a constrained check of a
specific chain, not open-ended pathfinding
- Right-first expansion is the default. If an empty result genuinely merits another
attempt, run left-first as a new, separately recorded query. Do not silently
change provider selection or expansion order after a failure and present the
second run as the first
Step 6: Federate only when you have a reason and can name the providers
- Federation is explicit and takes two to five named providers; it defaults to the
50-result cap
- Provider errors can coexist with useful results. Such a run is marked partial and
exits non-zero after retaining its artifacts — report it as partial rather than
as a clean negative
Step 7: Read the provenance, not the ordering
- Inspect the bounded summary for query-edge bindings and provenance, and the saved
TRAPI payload for the exact exchange
- Build the edge table: subject, predicate, qualifiers, object, supporting
publications, and knowledge source for each
- Position in the response is unscored response order. Describe it that way; calling
it a rank invents a confidence the service never expressed
- A zero result is "not returned under these constraints". Recording the constraints
is what makes that statement useful and what stops it being read as evidence of
absence
Step 8: Verify the load-bearing edges outside the graph
- Cross-check the same chain in PrimeKG, which is built differently — agreement
between two graphs that share an upstream source is not independent replication,
so check what each one's source actually was
- Pull the cited publications with paper-lookup and read them. A knowledge-graph
edge frequently rests on a single sentence in a review that was itself citing
something else, and the assertion can be weaker than its presence implies
- Confirm entity-level facts against primary resources with database-lookup
Step 9: Appraise and report
- Use scientific-critical-thinking to separate three things: what the graph asserts,
what the underlying literature supports, and what your hypothesis needs. They are
rarely the same set
- Analyse the retrieved subgraph locally with NetworkX if structure matters, and
keep it labelled as retrieved rather than inferred
- Write up with the CURIEs, categories, predicates, qualifiers, constraints, dates,
and knowledge sources attached to every claim, and state plainly that a returned
path is a candidate for verification, not a validated mechanism or clinical
guidance
Expected Output:
- Reviewed CURIE/category table for every entity, produced before any graph query
- Exact TRAPI payloads and bounded summaries per query, in separate directories
- Edge table with predicates, qualifiers, publications, and knowledge sources
- Independent verification notes from PrimeKG, primary databases, and the papers
- An appraisal separating graph assertion, literature support, and hypothesis need,
with constraints recorded for every negative result
