Been reading through this and I have two questions:
Is there a way to differentiate between IBS and IBD segments? I obviously know that smaller segments could be either but I would think IBS is still valuable particularly if one is looking for "what they are" rather than who they are related to? Or do I have that completely wrong?
That aside, I have noticed when I lower the threshold (cM wise), many of my Jewish matches are peppered with smaller matching segments, most of them seem to be bunched together with minimal spacing between them (i.e. one ends at 98.31 and the next begins at 98.39 with several others in succession). Many of these chromosomes have 10-18 matching segments.
Last, and I have not seen a good answer on this, are the number of SNPs valuable? For example, on one match I have a 2.1 cM segment with 4,153 SNPs while another is 7.1 cM with 812 SNPs.
