Dear Angsd authors,
I believe the formula for the Watterson estimator of theta should be fixed in the doc.
I got confused when reading it, and also by the formula written in Korneliussen et al. 2013.
The actual computation is doing the right thing though, here is the bit that matters:
angsd/misc/realSFS.cpp
Line 866 in 68b0838
so my modification is just about the documentation.
Best,
