I use this information at DNAPainter when painting the segments of matches with whom I can identify a common ancestor. If you want to sort a spreadsheet to look for all of your matches on specific areas of chromosomes, this is the best way to achieve that goal. I provided step-by-step instructions for this process at each of the vendors, here.ĭNA Segment File – This file contains the segment information with each of your matches, including the start and end locations of your matching segment(s), the total number of matching (shared) centiMorgans (cM) above the vendor’s matching threshold, and sometimes the longest segment. Raw DNA file – If you want to upload your DNA file to another vendor for matching at their site (MyHeritage and FamilyTreeDNA,) you’ll need to download your raw data file from the vendor where you tested. There are three types of files that you can potentially download from each of the major autosomal DNA testing vendors. If you’ve taken an autosomal DNA test and you’re working to determine how your matches are related to you, meaning which ancestors you share, you’ll want to download your DNA match list.
