Hi All, I am new to this list, I wondering is it source available for blastall executable from NCBI site. I am getting some error with the one of the parameter(Matrix value) to blastall. If that default file BLOSUM62 is available locally, then it is working, if I am running from some other location and specifing that file location, then it is giving error. [blastall] ERROR: gi|532319|pir|TVFV2E|TVFV2E: BlastKarlinBlkGappedCalc: test/BLOSUM62 is not a supported matrix any suggestion! help! -bala- __________________________________________________ Do you Yahoo!?
