.SH NAME
.PP
\f[B]vcfevenregions\f[R]
.SH SYNOPSIS
.PP
\f[B]vcfevenregions\f[R] options
.SH DESCRIPTION
.PP
Generates a list of regions, e.g.\ chr20:10..30 using the variant
density information provided in the VCF file to ensure that the regions
have even numbers of variants.
This can be use to reduce the variance in runtime when dividing variant
detection or genotyping by genomic coordinates.
.SH OPTIONS
.IP
.nf
\f[C]
options:
-f, --fasta-reference REF FASTA reference file to use to obtain primer sequences.
-n, --number-of-regions N The number of desired regions.
-p, --number-of-positions N The number of positions per region.
-o, --offset N Add an offset to region positioning, to avoid boundary
related artifacts in downstream processing.
-l, --overlap N The number of sites to overlap between regions. Default 0.
-s, --separator SEQ Specify string to use to separate region output. Default \[aq]-\[aq]
Type: transformation
