ptraj prints out a lot of status information, and without this I cannot
determine what is going on. Also, you do not have the correct format for
the mask strings which should be :67.OD1 :110.NZ. I also do not see why
you need to strip the :WAT residues as this is irrelevent (since you are
not outputing a new trajectory or doing anything after the strip). I
highly recommend, *again*, to go through the tutorials...
