[Bioperl-l] again on remove gapped columns

[Jer-Ming Chia]

The option for removing all-gaps columns was recently added into 
SimpleAlign.

=head2 remove_gaps

  Title     : remove_gaps
  Usage     : $aln2 = $aln->remove_gaps('-'[,$all_gaps_columns])
  Function  : Creates an aligment with gaps removed
  Returns   : a Bio::SimpleAlign object
  Args      : a gap character(optional) if no specified,
              taken from $self->gap_char, optional $all_gaps_columns flag
                         indicates that only all-gaps columns should be 
deleted

=cut

so check which bioperl release you have (you may need to grab it from 
the live branch), and try:

my $aln_nogaps = $aln = $aln->remove_gaps('-',1);
