Software to Help Identify Reference Profiles: mixSTR

MixSTR is an Excel-based tool that can help identify reference profiles in sets of mixed-source samples. Given allele lists for one or more evidentiary samples and all relevant suspect and control reference profiles, mixSTR provides detailed lists of the match and mismatch alleles among all samples and STR profiles. Sorted summaries of the percent of included alleles and loci for all comparisons are also provided. This tool is intended for use by forensic scientists working with mixed-source samples particularly cases involving a number of suspects. MixSTR was developed in collaboration with the Palm Beach County Sheriff's Office.
