The WS Genes track shows Sanger Gene predictions from the Wormbase v. WS190 files downloaded from the Sanger Institute FTP site, and then mapped onto the WS180 genome assembly. This track shows the subset of data annotated as "curated", or "Coding_transcript" followed by one of these strings: "intron", "coding_exon", "exon", "cds", "three_prime_UTR", or "five_prime_UTR" in the gff files.
The Sanger gene predictions are produced by WormBase. Thanks to the WormBase Consortium for providing these data.
