BLAST one sequence set against another set of
sequences. Each sequence of the query set is blasted
against the other set and the best hit is returned.
If no hit can be found for a query sequence null is
returned. Additionally you can specify all BLAST parameters.
Needs formatdb and blastall installed
on your machine and in the path!
Note: The identifiers of the sequences you are blasting against must be
in the FASTA Defline format. Otherwise the identifier if your subject hits look like
_1/$TMPDIR/DBXXX where the first number ist the index in the database sequence set starting with
number 1.
Samples of correctly formatted identifier lines are:
