TeXshade is an alignment shading software completely written in TeX/LaTeX which can process multiple sequence alignments in the .MSF and the .ALN file format. It provides in addition to common shading algorithms special shading modes featuring functional aspects, e.g. charge or hydropathy, and a plenitude of commands for handling shading colors, text styles, labels, legends and even allows the user to define completely new sha- ding modes. TeXshade combines highest flexibility and the habitual TeX output quality--with reasonable time expenditure. The author is Eric Beitz.
