How to do automated blast with mulitple sequences and BLAST each one individually???

Question

[jeccy.J]

Is there an automated program that can take mulitple sequences and BLAST each one individually???

You might want to add more information to your question. Do you want to do this in parallel? Do you want individual output files for each query? Is there a reason why you can't or do not want to parse a results file with multiple queries in it?

I want individual outputfile of each query. I want to do locally.

Can you explain why you want separate output files for each query? It's hard to imagine why this is necessary, given that parsing a single output file is quite easy.

Yes, BLAST will take a fasta file with multiple sequences and search each one against the target database.

I would set blast to tabular output, and write a simple script to chop it into single results.

The other option is to split the input fasta file into a single file per query sequence, and then run blast on each input file.
