@MOTHUR_OVERVIEW@

**Command Documenation**

The homova_ command calculates the homogeneity of molecular variance (HOMOVA) from a phylip_distance_matrix_, a nonparametric analog of Bartlett's test for homo- geneity of variance, which has been used in population genetics to test the hypothesis that the genetic diversity within two or more populations is homogeneous.

A design file partitions a list of names into groups.  It is a tab-delimited file with 2 columns: name and group, e.g. :
        ======= =======
        duck    bird
        cow     mammal
        pig     mammal
        goose   bird
        cobra   reptile
        ======= =======

The Make_Design tool can construct a design file from a Mothur dataset that contains group names.
