I won't have time to look at your specific issues until later. Here are two small .pdf (print) files that everyone should be able to view that are excerpts from two of the spreadsheets that relate to Chromo 2. This is from the Raw_Compare_Chromo2 spreadsheet. It is only one tab and doesn't do a lot but it does have 15,000 rows because that is about how many SNPs Chromo 2 reports for us. There is now way around that. The number of matches, no calls, differences, etc. are calcuated. In the spreadsheet itself you can select/autofilter on differences to see how any two people compare. https://dl.dropboxusercontent.com/u/17907527/Example_Chromo_2_Raw_compare.pdf This is second .pdf is an excerpt of a larger R1b-L21_SNPs spreadsheet that I will probably have to skinny down to an output only format. I'm trying to emulate the FTDNA project Y DNA SNP report. Unfortunately BISDNA doesn't have projects so we need something like this. This is the spreadsheet that is a work in progress that will have to handle the plethora of SNPs that are coming our way through Big Y and FG. I will add tabs for those two eventually and already have one that actually is a copy/paste of the R-L21plus project Y DNA SNP report. In the actual spreadsheet, I filter out all upstream SNPs to reduce the size of the Genetic Signature (Chromo 2 term) of positive SNPs. You can filter on the potentially relevant SNPs for patterns. https://dl.dropboxusercontent.com/u/17907527/Example_Chromo_2_Y_DNA_SNP_report.pdf Regards, Mike W
