The iGenomes are a collection of reference sequences and annotation files for commonly analyzed organisms. The files have been downloaded from Ensembl, NCBI, or UCSC. Chromosome names have been changed to be simple and consistent with the download source. Each iGenome is available as a compressed file that contains sequences and annotation files for a single genomic build of an organism.

For more information, see the iGenomes Overview.
