Dear "gc"
     I believe you can use Reformat.  The GCG manual says:

                If you edit hsp70.msf with a text editor to manually
                adjust the alignment, you must use Reformat to rewrite
                the MSF file so that it can be used with Wisconsin
                Package programs by using

                      % reformat -MSF hsp70.msf{*}

An MSF file with an incorrect checksum (but otherwise correct) would be
the same as one which has been changed with a text editor.  Reformat would
assume the sequence characters are meant to be correct and calculate a new
