Maybe I did not explain well my difficult, I inserted the .t file generated
by MrBayes with the 25% of the trees discarded in R. Then I tried, in R, to
creat a consensus tree using these commands:
read.nexus("infile.nex.run1.t", tree.names =NULL)
tree<-read.nexus("infile.nex.run1.t")
consensus(tree,p=0.95,check.labels = TRUE)
con<-consensus(tree,p=0.95,check.labels = TRUE)
plot(con)
I used redundant commands, but the consensus was plotted.
The problem is the consensus tree is unrooted, and I tried this command for
rooting it:
tree <- root(tree, "Bougainvillea_infesta") #Bougainvillea infesta is
outgroup
The problem I have three species of Bougainvillea as outgroup, and in the
consensus rooted (with one only species of Bougainvillea), Bougainvillea is
paraphyletic, and it is not true. I need force the monophyly of
Bougainvillea (as available in Beauti) but I didn't find the right command.
So, please, so someone know this commnad for root a tree with more than one
outgroup species, or root the tree with one outgroup species and then,
force the monophyly of the outgroup, if it has many species? Another
question is: is there a command which allows exporting the consensus with
the PP values?
Finally, I woud like to express my apologies to Vojtěch, please, forgive me!
Any problems, please, write me
