[phenixbb] Cryo_fit installation

Hi everyone, I was wondering if you could help me with installing cryo_fit on an Ubuntu machine. I followed the instructions here for the cryo_fit installation. Then, I tried to follow this guide to install gromacs_cryo_fit. However, I got stuck at the "Install using a provided script" step. Do I need to install GROMACS separately before proceeding? Any tips would be greatly appreciated! Many thanks, Omar
