Currently is installed MrBayes 3.2.6 version working with mpi 2.0

This one of the programs that we recommend to use with screen (enlace a la página) 

Once entered in cluster-ceab we open a screen session (for further details see [[Screen]])

Then qlogin 
```
qlogin -l h_vmem=4G 
```
or a qlogin with the number of processors with mpi environment 
```
qlogin -l h_vmem=4G -pe mpi 6
```
once in the node if we don't need mpi we can run MrBayes directly

/home/soft/mrbayes-3.2.6/src/mb

but if we have reserved some processor to use mpi we need to declare two variables first, just copy this two lines in the terminal.

```
PATH=/home/soft/openmpi-2.0.1/bin:$PATH
LD_LIBRARY_PATH=/home/soft/openmpi-2.0.1/lib:$LD_LIBRARY_PATH
```

and then run the program with the number of processor reserved in the qlogin:

```
$ mpirun -np 6 /home/soft/mrbayes-3.2.6/src/mb

                         (6 processors available)

```

if you have started screen you can close this terminal while the program is running and reatach it later to see if is finished. 

don't forget to close the screen session when finish

close MrBayes with 'q' and 'exit' twice, the first one to finish the qlogin and free the reserved resources and the second one to clos the screen terminal.
