The blast+ that I downloaded was the disk image version, don't know it tht means that it is 32 bit only?? I have noticed formatdb assign internal identifiers (increment int) to my sequences, and orginal ID appears later: >gnl|BL_ORD_ID|12 1234 Why is that? When I blast them to nt reference using megablast, the most reads map to the right species. Such systems need a schema that tells them how to store that information.

Troubleshooting "SeqIdParse Failure" errors The most frequent cause of SeqIdParse Failure errors come from the syntax of the FASTA definition lines in the source database file. Contact us about this article I started to run blast, locally on my machine, on 4 files with 1323, 210, 501, 166 fasta sequences each. Afterwards I try to obtain sequence from defined positions of the db.
I am trying to iterate over the list of sequences in the fasta file and do a sequence alignment of each sequence in one file with each sequence in the other. You seem to have CSS turned off.

It's a good idea to add a function that initializes the database for you to the application.
