marin-dna/vertebrate-v1-all

Human-anchored 255 bp vertebrate sequences from the Zoonomia 447-mammal Cactus alignment and UCSC hg38 MultiZ 100-way alignment. This draft covers the all region cohort with all species scope and preserves source FASTA/2bit letter case.

Anchor eligibility uses the pipeline's pinned phyloP conservation filter. Sequence case is independent of that filter: lowercase bases preserve source repeat masking, uppercase bases preserve source non-repeat-masked sequence, and conservation scores never rewrite emitted characters or case.

Produced by the commit-pinned vertebrate projection pipeline.

Splits

• —train: 240,128,926 rows; no chromosome-18 source anchors.
• —validation: 16,384 original-orientation chromosome-18 rows (4,194,304 tokens including BOS).

The selected target manifest contains 135 family-deduplicated projection targets; human reference rows are added separately once per anchor.
