Newbie question on BLAST methods - (Jul/23/2006 )

Hi,

Can someone please explain to me what are the following different BLAST technics. I read about these terms in bioinformatics articles I'm currently interested in: All-against-all BLAST, Pairwise BLAST.

Thanks.

All against all:
for every sequence you have align it to every other sequence and build profile accordingly see psi-blast paper.

Pairwise:
given a seed sequence and another sequence align them. If you have multiple sequences only the seed and the other protein will be aligned

Thanks for the response!
