Hello!

Just like Manik Mayur suggested, the problem should be the links:

Making links may fix the problem of finding executables if that link location is already in your path, but it won't fix your other environment variables, or perhaps if you used configure --prefix.

Gromacs gives you the possibility to create links to /usr/bin directory
(ot something similar). If you didn't do that, one of the option is
trying to run the programs using the full path. Instead of using
pdb2gmx, try to use /usr/local/gromacs/bin/pdb2gmx. Replace
"/usr/local/gromacs" with the directory where you install gromacs. If
you didn't choose anything it probably is /usr/local/gromacs.

Call "source /path/to/GMXRC", then go do science.

I hope this can help
