Junior B. c891a78541 Phase 1 co-folding WORKS: HDAC2/Zn validated (Boltz-2 on Modal)
First clear positive result in the project. Ran Phase 1 on Modal L4
(~$0.70). Boltz-2 P(binder), cofactors co-folded:
- HDAC2 (+Zn): vorinostat 0.9994 vs negatives ~0.1 -> PASS, decisive
- hemoglobin (+heme): voxelotor 0.46 -> PASS (weak; covalent/tetramer)
- PKR (+FBP/Mg): mitapivat 0.32 < hydroxyurea 0.40 -> FAIL (allosteric)

HDAC2/Zn is the exact case classical Vina failed (no metal term, 7.9A
redock). Co-folding handles the Zn-chelation chemistry -> the structure-
binding modality pivot (PLAN §12) is validated on its decisive test.

Engineering fixes that got it running: image needs cuequivariance kernels;
max_containers=1 so weights download once (parallel corrupted the shared-
Volume checkpoint); rank by P(binder) not affinity_pred_value (sign).

Adds docs/results/phase1_affinity.csv (committed; raw under data/ gitignored).

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
src/          identifiers, disease, drugs, scoring, provenance
tests/        scoring unit tests

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
