Well, though you can use brute force and write your own application,
there are still just 12 possible orders with Q at the end, and 12 with Q
at the start (two residues are [KR]) so you could create a pattern file
and use fuzzpro -pattern @filename on the command line.
For example (Q at the end only in this file)
Does that help?
