Hello, it appears that there is some kind of bimodal process in this data set–the “Region P” (blue square) samples form two groups. The confidence ellipsoid obscures this. I could just remove the ellipsoid, but I’d really rather do something more intelligent like break the Region P samples into two groups. However, just looking at the distance matrix (also attached as .tsv), I can’t really tell which samples belong to which group.
Has anyone encountered anything similar, where they discovered groupings within their sample groups that merit further investigation? I would at a minimum like to identify the samples in both clusters in order to see if they have anything in common (e.g. date of DNA isolation). Thanks!
