Hi Bob Is there more to read about FT DNA adding the STR markers or is it ,that these STRs were stripped out before and are being left in results now?

Previously if you sent your BigY test off to YFull for analysis, they would report some 500 STR values. According to the FTDNA forum, Ftdna use standard Sanger sequencing for getting STR results. Since Big Y is a Next Generation Sequencing (NGS) test, a different technology is involved. There were apparently issues with accuracy with the bigy derived str results so they weren't reported or useable for comparisons by FTDNA even if reported by YFull from the same BAM file. Whether they are now doing Sanger testing for the 111 or just using some of the 500 NGS STR results I can only guess, but your really getting minimal new data, just that it is incorporated in their database results. It would be nice if the external YFull STRs or external SNP results such as YSEQ panels could be entered in FTDNA, as there is no single repository that allows data from multiple YDNA providers to be compared. I would love to have all my and my matches external SNPs and STRs reported in my Haplogroup project.
