Y-STR Kit will analyse .BAM raw data file or VCF files and outputs in HTML file format with all Y-STR values. It supports build 37 (hg19). If you are selecting VCF file, it must have SNPs/indels and all confident sites (not just the variants). Currently supports FTDNA 111 Y-STR Markers.

The tool provides the following output,
  • Y-STR_Report.html - Output HTML Report
  • bam_chrY.vcf.gz - VCF output with Indels, SNPs and all confident sites.

Extract the download and click 'Y-STR Kit UI.exe'. Select the .BAM or VCF file and click ' Analysis'. After clicking ''Execute', a command prompt will automatically open and start executing series of commands.
