Human-anchored 255 bp vertebrate sequences from the Zoonomia 447-mammal Cactus alignment and official version-matched UCSC hg38-to-target liftOver chains.
This draft covers the cds region cohort with all species scope and preserves source FASTA/2bit letter case.
Non-human rows project only the central human nucleotide and extract the 255 bp target window centered on its unique mapped locus.
For the 28 non-mammalian targets, the stable ucsc_multiz100way… See the full description on the dataset page:
