MrBayes command file
This option allows you to provide a custom MrBayes command file. A command file may contain any command that is normally issued inside the MrBayes shell, with the difference that each command line is ended with a semi-colon.
You can use the following minimal example as a starting point for your own command files.
set autoclose=yes nowarn=yes;
lset nst=6 rates=propinv;
sumt Outputname=mrbayes_out Conformat=simple;
The consensus tree has to be named mrbayes_out. Otherwise ARB will not be able to import it.
It is not necessary to include any kind of data loading command. The selected sequences will be loaded automatically.
