scripts/build.sh

#!/usr/bin/env bash
# Exact recipe for this dataset. Every stage is deterministic (pinned OpenGenome2 revision, fixed seed and rate) and
# resumable (finished shards are skipped), so running all stages from scratch reproduces the files bit for bit.
#
# Usage (from the dataset root):  bash scripts/build.sh [stage ...]   stages: euk rest valid finalize stats baseline readme
#   default: all stages in that order. Env: PY (python, default python3), WORKERS (default 14).
#
# Two train passes, because the eukaryotic genomes were sampled before a bug in the window rule was found:
#   euk   ncbi_eukaryotic_genomes with --rule length_weighted: a window of length L is kept with probability
#         rate * L / 16384. Windows are 16384 bases except the last of each segment, so the realized rate is
#         0.964 x rate, slightly lower for segment ends (records are ~20 Mb, segments end at tags/contig breaks).
#   rest  every other subset with --rule per_base (each window kept with probability `rate`, any length).
# Both passes use the same seed, rate, window and held-out species (1%), so heldout/ is built by both.
