SEQALSV service is designed to facilitate calculation of sequence alignmets between a given sequence (query) and a library of provided sequences. Calculations are performed using Smith-Waterman and BLAST algorithms.
For SEQALSV processing all sequences (query sequence and a library) should be entered in FASTA format.
A sequence in FASTA format begins with a single-line description, followed by lines of sequence data. The description line is distinguished from the sequence data by a greater-than (">") symbol in the first column (see an example below): >Name RKNGLNVKMDYTPNSGQLVRNLLNGKYNIAVAGIDNVIAYQEGQVKEPVVNPDMFAFYGV KELKLDYELKPMDFSGIIPALQTKNVDLALAGITITDERKKAIDFSDGYYK
