[R-sig-phylo] ape chronos function returning pLL of -1E100

I'm trying to use chronos (ape version 5.2) to scale a tree of ~800 tips, with branch lengths derived from a RAxML analysis. I'm using 4 outgroup calibrations. When I run the analysis using t.og <- chronos(tree, lambda = 1, model = "relaxed", quiet = FALSE, calibration = dd.out) I

[R-sig-phylo] simulate a packed morphospace of landmark coordinates?

I'm trying to simulate different degrees of morphospace packing of geometric morphometric coordinates ("packing" defined, for the purposes of this exploration, as closely-abutting regions having minimal overlap with other species in the space), using a tree and an empirical input covariance
