Hello,
I am using bpp3 to estimate species limits in a group of snakes, using sequences from 4 nuclear loci. Despite using burnin periods and sampling lengths of 1 million generations, I am not getting convergence, and separate runs using different starting seeds differ widely in the species hypotheses they support.
Does anyone have any suggestions as to possible causes and solutions?
Many thanks,
Wolfgang Wüster
