Dear all, I have a primitive question, I am afraid. I want to run MrBayes on amino acid sequences with the predefined tree, as random trees run does not reach conversion. Nevertheless, I can not find the command on how to do it. All the manuals and tutorials I have found say "User-defined trees can be read into MrBayes by executing a Nexus file with a ”trees” block" . That is followed by 'startvals' and 'npert'. I understand how to set the parameters for using the tree, but how to introduce the tree to Mr Bayes?
shortly: HOW can I READ IN the existing tree in MrBayes?
*'usertree' command resulted in the error message: "Usertree command deprecated. Define the tree in a treeblock and use 'Startvals' instead. Error in command "Usertree".
