means keep in the step 2 the charge values from the step 1.
i.e. put -1 in the input

> Are these values good?

Yes

yes

No in the RESP input stage 1, again freeze all in stage 2
please, read the RESP documentation about intra-molecular restraints

- jump a line
- charge value for the group of atoms; nb of atoms in this group
- mol nb, atom number

in your case, it could be something like:

 -.8340 1
    1 1
   .4170 1
    1 2
   .4170 1
    1 3

etc for all TIP3P wat. in molecule 1...
Same idea for molecule 2 to 12

Concerning inter-molecule charge equivalencing keep only the value for the atom3
which have a zero in the atom set up i.e. the 1st, 2nd and last atoms, see
above...

The problem is that a new manual has to be written with new tutorials to explain
how to use it. I cannot do it now, impossible, to many stuffs to do before
that...
