  <help>

This tool performs three basic calculations: 

(1) Computes the number of heterozygotes
(2) Computes the ratio between heterozygotes and homozygotes
(3) Computes the total number of alleles in the input dataset

----

This tools is based on vcfhetcount, vcfhethomratio,and vcfcountalleles utilities from the VCFlib toolkit developed by Erik Garrison (https://github.com/ekg/vcflib).
