Abstract excerpt

The latest release of ForenSeq™ Universal Analysis Software (UAS), version 2.7.0, introduces several major upgrades, including the implementation of bracketed formatting for short tandem repeats (STRs) and adoption of the International Society for Forensic Genetics minimum STR reporting range. Among these features, a new filter was implemented to remove the X.1 artefacts observed at the D7S820 locus, thereby...
