Junior B. 9efdc0acf1 Pose-RMSD confirms HDAC2/vorinostat geometry: 0.21A (Vina was 7.9A)
Close the §12.4 validation loop. scripts/pose_rmsd.py superposes the
Boltz-2-predicted HDAC2 onto crystal 4LXZ, transforms the predicted
ligand, and scores pose RMSD (spyrmsd, in-place):
- protein fold: Ca RMSD 0.14A over 366 residues
- vorinostat pose: 0.21A (crystal-accurate) vs Vina 7.9A on this exact
  Zn-chelation case
- catalytic Zn ion: 2.73A off (ligand perfect, metal slightly less)

HDAC2 now validated on BOTH affinity (P(binder)=0.999) and geometry
(0.21A). The structure-binding modality is comprehensively validated on
its decisive metal-coordination case. Commits the predicted complex as
evidence (docs/results/HDAC2_vorinostat_pred.pdb).

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
docs/         recovery_test_report.md, data_sources.md, known_limitations.md

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
