This contains the following tools:

filter - remove unwanted sequences from a clustering
         usage: filter seq.list < cluster.L > cluster2.L
         cluster2.L will only contain sequence labels found in seq.list

hist   - produce a histogram of cluster sizes from a "label"-formatted
         clustering.

clusc  - compare clusterings, calculating jaccard and (hopefully
         correctly) rand indices.  More to follow as/when I need it.

xcerpt - given a file containing a list of sequence labels (e.g. a
         "label" formatted clustering), extract matching sequences
         from a fasta.file 

	 Usage: xcerpt list.txt fasta.seq
         creates "fasta.seq.match" and "fasta.seq.rest"
