MAPGAPS version 2.1

MAPGAPS: Multiply-Aligned Profiles for Global Alignment of Protein Sequences

Identifies and accurately aligns up to a million or more sequences, taking as input a database of fasta formatted protein sequences and, as the query, a hierarchical multiple sequence alignment (hiMSA), such as are available from the NCBI (see below).  MAPGAPS generated multiple sequence alignments (MSAs) are used as input by BPPS, SPARC and DARC.
