[galaxy-user] downloading a reference genome: Saccharomyces_cerevisiae_S288C_SGD2010

We have mapped our ABI SOLiD reads to the "Yeast (Saccharomyces cerevisiae) str. S288C: Saccharomyces_cerevisiae_S288C_SGD2010" reference in Galaxy, and need to compare our yeast genomes to the reference. We have tried to download the only S. cerevisiae S288c genome release listed at SGD for 2010 among their genome releases (http://downloads.yeastgenome.org/sequence/S288C_reference/genome_releases/S2...), but this does not align with the consensus sequences generated by mapping against Galaxy's "Saccharomyces_cerevisiae_S288C_SGD2010". Is Galaxy's Saccharomyces_cerevisiae_S288C_SGD2010 reference available for download from Galaxy or from the Saccharomyces Genome Database (SGD)? Best wishes, Douda
