Junior B. 0535886ce6 Phase 2 screen pilot: HDAC2 recovers the inhibitor class (P>=0.99)
Add the `screen` entrypoint (parallel ~10-wide, cached weights) and run a
24-drug pilot vs HDAC2 (+Zn), ranked by Boltz-2 P(binder). ~$1.3.

Result (recovery test at scale): top 9 are ALL HDAC inhibitors
(trichostatin-A/vorinostat/panobinostat/belinostat/scriptaid/mocetinostat/
entinostat/apicidin >=0.99; valproic-acid 0.91), clean drop-off to
hydroxyurea 0.78 and non-HDAC drugs to dexamethasone 0.03. Captures the
structure-activity gradient (hydroxamates > weak fatty-acid > non-HDAC).

Honest false negative: romidepsin (potent HDAC inhibitor) ranks low (0.43)
-- it's a depsipeptide PRODRUG co-folding doesn't model. Screen mishandles
non-standard chemotypes.

Screening pipeline validated; next is the full 300-drug discovery run.
max_containers=10 (parallel safe once weights cached).

Reverso MVP — Sickle Cell Repurposing Pipeline

A minimum viable drug repurposing pipeline for sickle cell disease: build a disease signature from public transcriptomic data, build drug profiles for ~300 small molecules, and rank them by CMap-style connectivity scoring. Validated by a recovery test — do the two known sickle cell drugs (hydroxyurea, L-glutamine) rank near the top?

See PLAN.md for the full specification, locked decisions, and week-by-week build plan.

Quickstart

# Requires Python >=3.11,<3.13 (see note below)
pip install -e .            # or: pip install -e ".[dev]" for test/lint tooling
pytest                      # run unit tests

Python version note: use Python 3.113.13 (python3.13 -m venv .venv). Python 3.14 is not yet supported by all pipeline dependencies (pydeseq2, cmapPy).

Project layout

data/         raw (downloaded, never edited) / processed / results — gitignored
notebooks/    01..05, run end-to-end in order

The deliverable

When complete, the artifact to share is three files:

  1. docs/recovery_test_report.md — the 2-page write-up
  2. data/results/ranked_candidates_v1.csv — the ranked drug list
  3. The signature + drug profile files with provenance
