Hi, Please get a non-PLUMED version working first. When you report a command line, please copy and paste it, rather than type it out and make typos. Probably you are running a version of GROMACS that was compiled to run on a different kind of node, but you need to find out what kinds of nodes your

Dear Mark and Justin, I've switched to function type 1 and the simulation runs. I thought the function type would correspond to the type of the comb-rule and missed the information given in the 5.8.1 section of the manual. Thanks a lot! Andreas Am 12.08.2016 um 14:15 schrieb Justin Lemkul:
