It has become necessary for us to modify the structure of the “releases” branch FTP site. The reason for this is that we are now required to represent potentially multiple alternative reference genomes sequences for a single nematode species (e.g. Ascaris suum).
In many cases, these references will originate from different strains, but that may not always be the case. We have therefore chosen to differentiate between alternative reference genomes for a single species by including the NCBI BioProject accession (http://www.ncbi.nlm.nih.gov/bioproject) in the directory path and files names. Alternative genome sequencing efforts for the same species will each be assigned their own unique NCBI BioProject accession.
