Wunderbar is a program which is able to identify mislabeled samples in genotype data when a few extra independent genotypes are available ("genetic barcoding"). Wunderbar calculates the likelihood that genotype mismatches have occurred by chance. It is capable of reliable and sensitive detection of sample mismatches and swaps even in the presence of numerous genotyping errors and in the presence of linkage disequibrilium between the individual genotypes. It only requires a few SNPs to work well.
