   Standard (Mandatory) qualifiers:
  [-sequence]          sequence   Sequence filename and optional format, or
                                  reference (input USA)
   -regions            range      [None] Regions to mask.
                                  A set of regions is specified by a set of
                                  pairs of positions.
                                  The positions are integers.
                                  They are separated by any non-digit,
                                  non-alpha character.
                                  Examples of region specifications are:
                                  24-45, 56-78
                                  1:45, 67=99;765..888
                                  1,5,8,10,23,45,57,99
  [-outseq]            seqout     [<sequence>.<format>] Sequence filename and
                                  optional format (output USA)

   Additional (Optional) qualifiers (* if not always prompted):
   -tolower            toggle     [N] The region can be 'masked' by converting
                                  the sequence characters to lower-case, some
                                  non-EMBOSS programs e.g. fasta can
                                  interpret this as a masked region. The
                                  sequence is unchanged apart from the case
                                  change. You might like to ensure that the
                                  whole sequence is in upper-case before
                                  masking the specified regions to lower-case
                                  by using the '-supper' flag.
*  -maskchar           string     ['X' for protein, 'N' for nucleic] Character
                                  to use when masking.
                                  Default is 'X' for protein sequences, 'N'
                                  for nucleic sequences.
                                  If the mask character is set to be the SPACE
                                  character or a null character, then the
                                  sequence is 'masked' by changing it to
                                  lower-case, just as with the '-lowercase'
                                  flag. (Any string from 1 to 1 characters)
