[Bioperl-l] remove gapped colums

[luisa pugliese]

Hi,
   I am new at bioperl and I am working on alignments. I am splitting a multiple alignment into several pairwise alignments and I would like to remove the columns in which there are gaps in all the sequences. Does anybody knows if a method exists doing this or a method finding the columns in which there are gaps in all the sequences similar gap_line that find the gaps present in any columns?
Thank you
