Dear Andreas, Perhaps the thing you need to do is to let us exclude some of our matches who share long segments with us (first and 2nd cousins in particular). We don't want their really long segments to determine the size of the triangulated groups. Perhaps you will want to create an upper threshold for the length of a triangulated group in the range of 40 to 50 cMs or so.

Reason is that each user is part of many TG’s and having different threshold amongst your TG won’t work. Also we differentiate ourselves by making many difficult to understand decisions for the user. People don’t understand the thresholds in GEDmatch, it’s a tool for few but not for the masses.

No information is lost, we do have the info from the closer cousins/parents who are indeed holding those smaller TG’s together.The chromosomes map which we build up automatically is key as it shows those close and far MRCA’s.I think there is still work to be done to try out which threshold is the best one for TG’s and when one should stop splitting them up further.Andreas > > ------------------------------- > To unsubscribe from the list, please send an email to [email protected] with the word 'unsubscribe' without the quotes in the subject and the body of the message ------------------------------- To unsubscribe from the list, please send an email to [email protected] with the word 'unsubscribe' without the quotes in the subject and the body of the message
