The monomer count determination only works for simple cases. If you know what 
it should be, enter your own value.

You command file indeed does not turn on ncsmask updating, and so dm should 
not be updating the averaging mask. However it will still calculate a solvent 
mask every cycle. Are you sure you are not looking at this?

Also, turn of the 'MULT' option, it is obsolete.
