bolinas-dna/genomes-v5-validation-intervals-v5_255_255

Conservation-encoded human validation probe for the v5 (CDS) region recipe, matched to the bolinas-dna/genomes-v5-genome_set-*-intervals-v5_255_128 training sets. Produced by the `snakemake/training_dataset` pipeline (commit `8db58254831f`).

Size

16,384 sequences in validation.parquet (a subsample of up to 16,384 human windows). Exact row count — HuggingFace's auto-generated count can be wrong.

Region recipe: v5

Coding sequence (CDS): every annotated CDS interval, kept if 20 bp–10 kb long, extended by 20 bp on each side (to capture splice-site signal at exon boundaries), then expanded to a minimum length of 256 bp and intersected with defined.

Built on the human genome (GRCh38 / GCF_000001405.40).

Schema

A single validation.parquet. Each row:

FieldTypeDescription
idstr{chrom}:{start}-{end} — 0-based half-open, bare RefSeq chrom names.
seqstr255 bp DNA with conservation-encoded case (see below).

Sequence case = phyloP conservation

Each base's case is overwritten to encode conservation (the source soft-masking is discarded):

  • —Uppercase — phyloP-241way (Cactus 241-way alignment) score ≥ 2.27 at this position (conserved).
  • —Lowercase — score < 2.27, or there is no alignment / the score is missing (NaN, which compares false). Non-conserved and unaligned bases are not distinguished.
⚠️ This is the opposite convention to the training sets, where lowercase means repeat-masked, not non-conserved.

Construction

  1. 1.Build the v5 interval set on the human genome and tile into 255 bp / 255 bp (non-overlapping) windows.
  2. 2.Subsample up to 16384 windows (seed 42).
  3. 3.Re-encode each base's case by phyloP-241way ≥ 2.27.
