Summary | 0006835: Creating dummy outgroup for using RelTime with tree of life data | ||||||||
Description | Hello, I am interested in using RelTime-BranchLengths to estimate dates for a tree-of-life dataset. As such, there is no formal outgroup in the tree. If I were to add a dummy outgroup to the tree (1 taxon or a small clade), could I run RelTime-BranchLengths analysis with calibrations enabled on the "real" tree-of-life ingroup? Any advice on this would be appreciated! Best, Charley. | ||||||||

Hi Charley, I am writing in response to your question regarding the Reltime analysis in the MEGA software. Yes, you can add a "dummy" outgroup since the Reltime analysis will only use branch lengths from the ingroup. Best regards, Glen Stecher |
