StatsX v2.0: the interactive graphical software for population statistics on X-STR

Short Communication


StatsX (Statistics for X-STR) v2.0 is developed to facilitate the workflow for analysis of population data on X-chromosomal short tandem repeat (X-STR) marker. The interactive graphical and installable software can estimate allele/haplotype frequencies from female, male, and pooled samples and calculate forensic parameters by importing a single file. In addition, it is able to filter out the invalid raw data and export a series of pre-formatted Arlequin input files that are directly used for testing the significance of the Hardy–Weinberg equilibrium (HWE), linkage disequilibrium (LD), and gender differentiation. As expected, all results of frequencies and forensic parameters can be saved as EXCEL workbooks and also plotted as bar or line graphs. Further, full concordance was obtained by recalculating frequencies and forensic parameters with other established software from a published Han Chinese population.
