Sequence alignment

Below is shown a dump of the four matrices used to make the sequence alignment of two fasta files. You can use this to compare the output from you fasta_align_O3 and fasta_align program. The output was made aligning two small fasta files q1.fsa and q2.fsa.

First copy these two fasta files to your data directory

cd 
cd data
cp /home/projects/mniel/ALGO/data/Align/q?.fsa .

Next run the command

fasta_align_O3 -show -gf 2 -gn 1 q1.fsa q2.fsa

The output to the screen should look like

# Gap penalties. fgap: 2.000000. ngap: 1.000000

Next you can do the same for the fasta_align program

fasta_align -show -gf 2 -gn 1 q1.fsa q2.fsa

The output to the screen should look like
