High throughput sequencing is generating large datasets that can be used provide important insights into genomic variation and biology. There is a need to visualize single nucleotide polymorphisms, insertions and deletions, and other structural variants from new sequence file formats. We have developed VarB software that can read in multi-sample VCF files, and visualize and critically assess contents and identify informative markers to discriminate between user-defined groups. The C++-based software VarB was developed by Mark Preston and Magnus Manske, and is available from:
