MULtiple ALignment by BLAst :
This tool will attempt to perform a pseudo-multiple alignment on two or more sequences using gapped-BLAST version 2 capabilities.

How it works:
Given a an input of 2 or more sequences in the upper field, one of them will be blasted against the others. If there is no guide sequence (entered in the lower field) the best alignment is selected as follows: each sequence to be aligned is blasted against all others, and sum of all scores determines the best alignment.

Enter sequences to be aligned below : (two or more sequences required /fasta format)

 




Enter here sequences to be aligned. If no guide sequence is provided, the higthest sum of score values determines the best alignment.


Enter one guide sequence to force alignment: (optional / fasta format )

Sequence provided in this field , if any, will be used as a guide for multiple alignment
