Hi all,

I am trying to use runSurface {surface} but I get the next error:

> runSurface(tree, data)
Error in runSurface(tree.nex, data) :
Each node in 'tree' must have a unique label for back-compatibility between formats. Use 'nameNodes(tree)'.


When I use nameNodes(tree):

Phylogenetic tree with 113 tips and 112 internal nodes.

Tip labels:
Pinus_clausa, Pinus_banksiana, Pinus_contorta, Pinus_virginiana, Pinus_sabiniana, Pinus_coulteri, ...
Node labels:
    zzz1, zzz2, zzz3, zzz4, zzz5, zzz6, ...

Rooted; includes branch lengths.

I understand that nodes haves differents labels, then what is the problem?

Thanks in advanced

Diego
