/afs/bx.psu.edu/depot/data/galaxy/blastdb_archive/downloads/2011_README_LOG This directory should contain 3 files for each database. We have decided to keep the previous two megablast database files, in case people need them later. So these are the originally downloaded gzipped fasta files (before any modifications) for the currently available ones and the previous two, for each database. The naming convention used is __.gz, like htgs_02jul2011_09jul2011.gz. We downloaded the htgs.gz file on July 9, and it was datestamped July 2.
