[gmx-users] Where can I get .gro and .itp files for different models of water?

Dear Gromacs users,
I am making tutorial on GROMACS but I can't find mdcourse folder in my installed software. I've taken spc.gro from spc.pdb from tutor folder.
I wonder where can I get spc.itp and spc216.gro?
In tutorial it is reffered to mdcourse directory, but I don't have such a directory.
I also wonder where I can get TIP3P.gro and .itp files and also the same TIP4P files.
