Enter the charges to be converted to dummy amino acids, 1 line per sequence.
eg.
.+.......+......+....-++-....-.--....+...+.-.........-....-.....-.-......-+--.........++...+-...+.+..-......+-+
..-+...................+.-......--+.-+....-....+....-..---..+....-..-.......-..-.......+.+
.-+.................+.-.....--+.-+....-....+....-..---..+....-..-...
'+' will be converted to 'K', '-' will be converted to 'E', '.' will be converted to 'G', ' ' will be converted to '-'.
You can then copy-and-paste the converted output into your favourite multiple sequence alignment program,
and do a multiple sequence alignment for these charges as dummy amino acid residues.
Then copy-and-paste the aligned sequences back onto this page
and click the 'convert from residues to charges' radio button
to convert the aligned dummy residues back to charges.
