Dear all,
I am currently preparing a molecular phylogenetics course for our lab members, also including a tutorial on IQ-TREE 2. I came across the tip "Starting with version 1.5.4, -m MFP is the default behavior. Thus, this run is equivalent to iqtree -s example.phy" at https://iqtree.github.io/doc/Tutorial. I now noted, however, that both commands give different phylogenies and branch lengths, resulting from different best-fit models selected. So is that "tip" on the website not valid for IQ-TREE2?
Thank you and best wishes
