Fatal exception: subtrees' taxa overlap

[Advaldo Neto]

Hello, everybody!

I was trying to run Beast v1.8.2, but I received the error massage below.

Fatal exception: subtrees' taxa overlap

java.lang.RuntimeException: subtrees' taxa overlap

What could be wrong with my taxa?

I was using several fossil calibrations for TMRCA and some of them present the same taxa. (e.g.: calibration point for Fabaceae family and for Ingeae tribe present Inga genus). Is this the problem?

Thanks!

Hi,

The simulator that creates the starting tree respects the taxon sets that you have asked to be monophyletic. This error means that it has found that one or taxon sets are not compatible with each other (they should either have no taxa in common or one should be a subset of the other).

Best,

Andrew

Hi,

I am able to run the shared xml file below, but I need to modify the file to include two additional taxon sets and calibration priors in the attached text file.  When I add either taxon set, I receive the error that subtrees taxa overlap.  However, from the taxon sets I already have assigned, numerous taxa already overlap, but no error is generated.  I did not constrain monophyly in the taxon sets because it was also generating an error.

Unfortunately, the xml file is large so I have to share it via google drive:

Thanks,

Alex
