Hi users:
I run pure water MD. I need to run different water models. How can i get spce.gro, which means how can i get .gro of spce water? How can i get .gro of TIP4P?

The answer to both of these questions can be found here:

http://www.gromacs.org/Documentation/How-tos/TIP3P_coordinate_file

If i select TIP4P water model, which force field should i select? you know, i need .top, and .top should include force field. If i select SPCE water model, which force field should i select?

Water models, in principle, are not force field-dependent. In theory you should be able to use any of them.

I can find a spc216.gro, which is default solvent. I can use genbox to generate a box of solvent (spc water). how can we use other solvent, so we need to have the .gro of the solvent.

See the link above.
