Dear Gihan, The most likely thing I can think of is that the sequence contains a character not recognised as a legitimate one-letter code. This could happen if you use a special letter coding for an ambiguous residue, or if you say it’s a nucleic acid sequence instead of a protein sequence.
Something else we have seen occasionally is that people save a sequence file from a program that writes rich text format or something other than pure text. You could try looking at the file with a pure text editor, or using the “file” command from the terminal on a Unix (Linux, Mac) system. If neither of these explain the problem, please send the offending sequence file to me (off-list) and I’ll see if I can find out what’s wrong. Best wishes, Randy Read ----- Randy J.
