**What it does**

CallVariants is a high-speed, multithreaded variant caller that accepts bam files, and output VCF files.  It is capable
of indel realignment, multi-sample variant-calling, and processing samples with arbitrary ploidy.

BBMap is the recommended mapping program for CallVariants, but output from any aligner is acceptable.  Reads can be
realigned with the "realign" flag.  This is slower, but is highly recommended if the input is from any mapping tool
other than BBMap. Output from BBMap should not be realigned.

**Options**

 * **Ploidy** - Arbitrary ploidy is supported - the default is 1 which works for haploid organisms.  Allele fractions lower than those expected for the ploidy (for example, anything below 0.5 for a diploid, or 0.25 for a tetraploid) will incur a score penalty. When calling variants on non-haploid organisms, it is crucial to set the ploidy.
