cluster_aggd command

The cluster_aggd command performs agglomerative clustering of a distance matrix in tabbed pairs format.

The calc_distmx command can be used to calculate a distance matrix for sequences.

The beta_div command can be used to calcualte a distance matrix for samples in an OTU table.

Cluster linkage is specified using the -linkage option, which may be set to max (the default), min or avg.

Output is reported as a tree in Newick format specified by the -treeout option and/or as a clusters file specified by the -clusterout option. If a clusters file is specified, then the -id option must be given to specify the identity threshold.
