bonjour ,
je pensais mettre la racine de mon arbre au niveau du noeud 0.99séparant les bacteria -proteobacteria gamma des bacteria proteobacteriabeta (groupe externe)
Pour cela j'ai copié les BPBRRA1-E-value2e-92-Bacteria-Proteobacteria-Betap BPBNCV1-E-value3e-94-Bacteria-Proteobacteria-Betap qui se situent cg-hacune de chaque côté du noeud 0,92 mais cela ne modifie pas l'enracinement
Pouvez vous m'aider?

Width of the tree (number of letters):
Truncate leaf labels to (number of letters):
Collapse branches with support values below (enter 0 not to collapse):
Display as cladogram (ignore branch lengths, in case the tree topology is difficult to see for very short branch lengths): no yes
Re-order leaves : alphanumeric order of labels number of descendants (nodes with fewer descendans appear first) de-ladderize (alternately put nodes with fewer descendants before or after those with more)
Add a spacer in leaf names (in case the leaf names get written over by robustness values) : no yes
Root the tree on the following (give the full name of one or more sequences from the branch you want to root on):
