Hi all,

I have an FastME NJ error. I have a matrix where the distance between two of the taxa is unknown. So far, none of the NJ versions can seem to handle this. I tried FastME and BioNJ. Please help!!

Your matrix is not good, you need to have a distance for all your pairs.

I got the matrix from 25 fasta files. One file represented one gene. There was no file that had both taxa 14 and taxa 7, hence the missing data. I am not sure how to account for that case.

Try DAMBE, which implements a method to impute missing distances.
