Dear Hamed,
1. Regarding your first question, I would change the compilation
option for resp and try something like:
-mcmodel=medium or even -mcmodel=large
That will change the way memory is handled and should
allow for larger arrays of data.
2. Regarding your second question, you figured it out right:
- maxmol is the maximum number of molecules.
- maxq is the maximum number of charge centers of all molecules
considered together.
- maxlgr is the maximum number of charge constraints you want
to apply.
You have to consider in this number not only the charges imposed
to each molecule of your set but also all the intra- and inter-molecular
charge constraints.
I hope this helps.
Cheers.
JPB.
