Can this be done for QM/MM?

Hey, this isn't difficult.
In case of Amber files use Parmed and something like
Parmed
>parm my.prmtop
>HMassRepartition
>outparm my.heave.prmtop
In case of charm you can use the new function of psfgen in VMD:
TkConsole
>package require psfgen
>resetpsf
>readpsf my.psf
>hmassrepart
>writepsf my.heavy.psf
In NAMD, you don't have to change much, simply set:
timestep 4
fullelectfrequency 1
nonbondedfreq 1
and of course use the heavy topology you created.
Have fun!

Does anyone have a tutorial on how to implement hydrogen mass repartitioning
in NAMD? I have never used this method before. Thanks!
