=====================================
 bcftools @EXECUTABLE@
=====================================

Parses VCF or BCF and produces stats which can be plotted using plot-vcfstats. 

When two files are given, the program generates separate stats for intersection and the complements. 
By default only sites are compared, -s/-S must given to include also sample columns.

When one VCF file is specified, then stats by non-reference allele frequency, depth distribution, stats by quality and per-sample counts, singleton stats, etc. are printed. When two VCF files are given, then stats such as concordance (Genotype concordance by non-reference allele frequency, Genotype concordance by sample, Non-Reference Discordance) and correlation are also printed. Per-site discordance (PSD) is also printed in --verbose mode.
