This is a rather basic question, but since I am confronted with a rather complicated scenario I have problems wrapping my head around it.
I have calculated pairwise psi values of 6 populations. The output looks like this:
0.000000000 | 0.0255514910 | 0.0019620907 | 0.0032395251 | 0.0270943481 | 0.10144639

Now I wonder about the direction of expansion. E.g. there seems to be a signal of expansion between 1 and 6 (psi=0.10144639 / -0.101446393; these values are also significant based on permutation test), but I do not know where it started. Are the source populations (S1/S2) given in rows or the columns?

Hi Erica. I am fairly sure that the columns represent the source populations. I think so, because I calculated the most likely origin and if the source populations were in the rows, the direction of my psi values and the inferred origin would not fit together at all.
