Dear Sandrine, Thanks for pointing out this issue. The BLAST databases we have on Galaxy are from last year, while those on NCBI website are the latest (Jan 2012). As pointed out on NCBI website (, it appears that each time any change is made to a sequence/database, GI numbers change as well. This is perhaps why you're observing discrepancies in GI numbers and lengths between megablast outputs on Galaxy and NCBI. I'm currently in the process of downloading the latest BLAST databases from NCBI, and I'll let you know when they're available for use on Galaxy. Thanks for your patience, Guru Galaxy team.

Hello all, Did this issue get resolved? If Sandrine was right about there being an off by one error in GI number in the BLAST tabular output, it could be a bug in 'legacy' blastall command. I say 'legacy' BLAST because that's what Galay's NGS 'megablast' tool is using internally (as opposed to the the NCBI's replacement BLAST+). Peter
