Hello, I recently downloaded and installed gromacs-3.1.4-1.i386.rpm, and fftw-2.1.3-1.i386.rpm. I have been unable to find the nmrun program that is found in the gromacs documentation. I can run the gmxdemo tutor fine. In addition, g_nmeig, g_anaeig, and g_nmens all appear to work fine, I just can't find nmrun. Any ideas? Thanks, Mark Fleharty
