Abstract
A suite of some dozen programmes written in FORTRAN77 to run on VAX computers using the VMS operating system, and which utilizes a Digital Command Language (DCL) shell to allow it to be menu driven has been in use at the Division of Molecular Biology for about nine months. The package allows the user to obtain both dot matrix and line matrix plots, find and output specific regions of similarity and compute statistics for randomly generated sequences. In all these cases the user may specify either a maximum number of gaps in the match that will be tolerated or a minimum percentage similarity allowable for a match to be registered. The system allows the user to create a batch job for any of these analyses; so, for example, a number of line matrix plots can be specified from a remote alpha-numeric terminal which can be plotted later at a graphics terminal. In addition, computation of quasi-correlation statistics (Qr) for nucleotide sequences or correlation statistics (r) for amino acid residue sequences may be computed. Help facilities and documentation including examples are provided.
