If you're using the "megablast" tool in Galaxy, then it will be NCBI "legacy" BLAST using the blastall binary. If you're using the (commented out by default) BLAST+ wrappers, then it will be using the blastn binary. There were changes to the ID handling in the tabular output in BLAST 2.2.25+ as I recall. Another important factor is how the BLAST database was made (with or without the -parse_seqids flag). Peter P.S. Questions like this about local installs might be better on the galaxy-dev list, CC'd. ****************************** Thanks Peter, I debated which to post to. This is just using the Megablast tool in Galaxy. My IT people are not Biologists. They had this working fine and some tweak has screwed up the GI column in the results file. It should be the same NR and HTGS datafiles that we had before. So you recommend that I should just have them reinstall the databases and make sure to use the correct switches?
