ALIGNMENT SERVICE: creation and processing of alignments of sequences of unlimited length

A package for the creation and processing of multiple sequence alignment is described. There is no limit on the lengths of the processed nucleotide or amino acid sequences, and the number of sequences in the alignment is also unlimited. The main groups of functions are: a semiautomatic alignment editor; a wide set of functions for technical processing of alignments; nucleotide alignment mapping and translation; and similarity search functions. A user-friendly interface and a set of generally used file actions provide a special operational subsystem for everyday tasks.
