Hi all,
I'm running the new version of MrBayes and I'm using Mega to look at the resulting tree. I noticed that MrBayes automatically includes a translate block in the tre file, substituting the taxa labels by numbers. However, I'd much rather have the original taxa labels in my tree than these numbers. Does anybody know how to avoid this from happening? This hasn't been a problem with earlier versions of MrBayes.
Thanks!
Hi Laura,
The problem is not so much with MrBayes, but rather with MEGA as a tree viewer. MrBayes does include the Translate block to store all the sampled and consensus trees from mcmc run in a more efficient way. Most tree viewer programs (FigTree, TreeGraph, TreeView, Mesquite, etc.) have no problems reading tree files with such Translate blocks and show your OTUs with the original taxa labels; MEGA only reads the newick trees from your tree files but not the Translate block, so it shows your trees with numbered OTUs as they appear in the newick format. I've been using Mesquite and FigTree to visualise trees from the new MrBayes and had no problems with taxa labels (these programs also offer more options to edit, format, and analyse trees).
Cheers,
Oksana
Thanks guys, opening the file with Figtree does the trick!
Cheers, Laura
