Matthias, GROMACS only writes to a file when the amount of data reaches a certain threshold, prior to that it is just stored in memory. I don't know what that chunk size is. It may be the manner in which the analysis script stores the trajectory data in memory? Hopefully a developer will be

[gmx-users] gmx angle memory consumption

2017-11-21 Thread Matthias Ernst
Hi, I want to calculate dihedral angles for long trajectories at high sampling rates using gmx angle as follows: gmx angle -f traj.xtc -n dih_indices.ndx -ov dih.xvg -type dihedral -all After some time, it completely fills my RAM without having written anything to the output file. As the
