Sequence searches

Blast

We searched the "big80" database with Blast with the following command:

blastall -p blastp -d /mnt/project/pracstrucfunc12/data/big/big_80 -i P06280.fasta -m 0 -o blastsearch_default.out -v 700 -b 700

The run took about 2 minutes (see section Time)

HHblits / HHsearch

We searched the "big80" database with HHblits with the following command:

hhblits -i ../P06280.fasta -d /mnt/project/pracstrucfunc12/data/hhblits/uniprot20_current -e 0.003 -o hhblits_default.out -E 0.003 -Ofas hhblits_msa_default.txt -z 700 &

The run took about 2.5 minutes (see section Time)

Also, we ran HHblits with 8 iterations, instead of the preset 2. This took 14 minutes.

hhblits -i ~/Desktop/P06280.fasta -d /mnt/project/pracstrucfunc12/data/hhblits/uniprot20_current -e 0.003 -o hhblits_default_n8.out -E 0.003 -n 8

Time

We evaluated the time the programs ran with the command "time"


Method Parameter Time
Blast v = 700 b = 700, v = 700 1m53.944s
HHBlits default 2m19.519s
HHBlits n = 8 13m49.545s
