Hi all, does Gromacs use the GNU readline library, so that I may "navigate" in the commands I give to e.g. gmx select using the arrow keys? Or did I do something wrong in my compilation? Cheers, Peter p.s. cmake .. -DCMAKE_INSTALL_PREFIX="/usr/local/$VERNAME" -DGMX_X11=ON -DGMX_BUILD_OWN_FFTW=ON -DGMX_GPU=ON
