Dear All, I am trying to run Medusa on a large phylogeny with 8,000 tips. When I give the species richness values in a CSV file, I get the following error message shortly after the analysis reports the AICc threshold: Error in optimize(f = foo, interval = c(log(par[1]/2), log(maxVal))) : invalid 'xmax' value If I remove the richness flag, the analysis runs as its supposed to. Has anyone seen this problem before? Am I merely trying to run the analysis with too big of a tree? Thanks for any input. Jacob
