MOTIVATION: Large genomic datasets combining genotype and sequence data, such as 
for expression quantitative trait loci (eQTL) detection, require perfect 
matching between both data types.
RESULTS: We described here MBV (Match BAM to VCF); a method to quickly solve 
sample mislabeling and detect cross-sample contamination and PCR amplification 
bias.
AVAILABILITY AND IMPLEMENTATION: MBV is implemented in C ++ as an independent 
component of the QTLtools software package, the binary and source codes are 
freely available at https://qtltools.github.io/qtltools/ .
