MM_KIND/QM_KIND atom type

[Luca]

I Fawzi,
it was only a fast test for QMMM procedure and with COMMENSURATE
keyword "works".
I have in mind a cutoff of 260-280 Ry
or greater, for organic molecules with H,C,O,N atom kind. Is it right?
....but I am going to
read article "QUICKSTEP: Fast and accurate....."
for more details.

Thanks,
Luca
