IS there an option in mothur for removing OTU-s that contain less than n sequences. Right now I would like to after clustering and before continuing to remove all OTU-s that have only a single sequence in it. Sometimes it might be useful to remove maybe all OTU-s that have lets say less than 10 sequences in them - or less than 1% of all sequences etc.  
If there is not such an option, then by which workaround might it be most easily accomplished. Also if there isn’t such a feature Im going to post it as a feature request.
