ALMA, an editor for large sequence alignments

Abstract

A dedicated sequence editor ALMA, was developed for aligning many sequences of proteins or RNA molecules or longer DNA fragments. Like previously published editors, ALMA is menu directed, screen oriented, and offers similarity and consensus display. ALMA has the additional features of collective movement of sequences, acceptance of input from many sources including structure files and databases, secondary structure display, and easy merging of alignments. In order to maintain sequence integrity and save disk space, gaps and sequences are stored separately. Automatic recovery of a session is possible. Finally, The program allows interaction between manual and automatic alignment.
