MC-QS-NPT calculations

Hello.  I can see the problem with change A.  When you change from 
TRADITIONAL to NPT_GEMC, you are changing the number of simulation boxes 
from 1 to 2.  In order to do the second box, it needs an additional input 
file, whose name is given by BOX2_FILE_NAME.  MC_QS.inp doesn't have that 
field in it, so it tries to open a blank file and then crashes with the 
error you're seeing.  You need to make another file, perhaps MC_QS_2.inp, 
and add a line for BOX2_FILE_NAME to both files.  BOX2_FILE_NAME for 
MC_QS.inp will be MC_QS_2.inp, and BOX2_FILE_NAME for MC_QS_2.inp will be 
MC_QS.inp.  Then each file knows about the other and CP2K can create two 
simulation boxes.

The problem with action B is related to that as well.  You have made it so 
that there is only one molecule type in box 1 (water).  However, when CP2K 
goes to box 2, it sees that argon is present as well.  If you add the 
following section to box 1 (and be sure that BOX2_FILE_NAME is correct in 
both boxes) and add the DFT stuff to box 2 as well, it should work.

        &MOLECULE
          NMOL 0
          CONN_FILE_NAME topology_fist_ARG.psf
        &END

Make sure the NMOL is correct for the number of molecules of that type in 
the box.  Also be sure that all the molecules are included together, and 
that they are arranged in the coordinate section to be in the same order 
that they are in the TOPOLOGY section.  Does that make sense?

                          Cheers, Matt
