Dear all,

I am new using VMD and MDFF. I am trying to do a flexible fitting of an
atomic structure into a cryo-EM low resolution volume following the
tutorial, but I get already stuck running on the VDM console the mdff sim
to obtain a simulate map out of the pdb.
I use the following command:

mdff sim $sel -res 5 -o map.situs

And I got the following error:

invalid command name "voltool"

I would really much appreciate your helpĀ·

Kind regards,
