Group Protein adjusts the spacing of protein sequences and adds numbering.

Group Protein adjusts the spacing of protein sequences and adds numbering. You can specify the group size (the number of residues per group), as well as the number of residues per line. The output of this program can serve as a convenient reference, since the numbering and spacing allows you to quickly locate specific residues.
