Dear Gontran, for short sequences such a result can happen. Maybe you check whether any values in dist.dna(seq100b, model = "raw") are close to 0.75. I suspect that some elements in this distance matrix are close to 0.75 than pairwise distances for the bootstrap samples are likely to be equal or g

[R-sig-phylo] Deadline extension for full talk abstracts for Conference on Informatics for Phylogenetics, Evolution, and Biodiversity (iEvoBio)

The deadline for submitting abstracts for full talks to the inaugural conference on Informatics for Phylogenetics, Evolution, and Biodiversity (iEvoBio) has been extended by one week to Friday, March 25, 2011. We hope that this will give those interested in contributing sufficient time to d

[R-sig-phylo] bootstrapping with boot.phylo()

Dear all, When I make a bootstrapping analysis of relatively short DNA sequences (100bp), I have an error message: Error in bionj(dist.dna(seq100b, model = "K80", pairwise.deletion = FALSE, : NA/NaN/Inf in foreign function call (arg 1) I am not able to solve the problem since: 1)This "short s
