Beyond our 230 or so natively hosted assemblies, our GenArk collection offers more than 50,000 NCBI assemblies, each already built with gene annotation and, for most eukaryotes, repeat annotation and alignments. We also curate more than 100 public track hubs that you can attach with one click from My Data then Track Hubs.
