[Bioperl-l] Remove columns containing more than 75% gaps in an alignment

[Daniel Gerlach]

Hello,

Is it possible to remove only columns containing e.g. more than 75% gaps 
from an alignment? I was thinking at

$aln2 = $aln->remove_gaps('-'[,$all_gaps_columns])

This would allow me to remove all gaps or gap-only columns but not using 
a threshold.

Greetings, Daniel
