BLASTP

Run BlastP on student machines with big_80 database.

Command:

blastall -p blastp -d /mnt/project/pracstrucfunc12/data/big/big_80 -i P45381_wt.fasta -o blastp_p45381_wt_big80.out

-p specifies the blast type
-d database
-i input file
-o output file

We got 195 resulting sequences, out of which the last 101 have EValues below E^-15.
