Robust sequence alignment using evolutionary rates coupled with an amino acid substitution matrix.

abstract：BACKGROUND:In bioinformatics community, many tasks associate with matching a set of protein query sequences in large sequence datasets. To conduct multiple queries in the database, a common used method is to run BLAST on each original querey or on the concatenated queries. It is inefficient since it doesn't exploit the...
