All microsatellite analysis software expects allele sizes given in integer numbers, while allele scoring produces allele sizes with two decimals that are dependent not only on fragment length, but also on fluorescent dye, and GC content. Therefore, allele binning is not a trivial task. Tandem2 fills a gap of the microsatellite workflow by rounding allele sizes to valid integers, depending on the microsatellite repeat units.
