[gmx-users] Segmentation Fault in EM
Hi all, I have been running alot of simulations on protein ligand interactions, and my settings/setup/mdp files worked great for one system. Then when we moved to a larger and more complicated system we started getting mdrun segmentation faults during steep energy minimization. This happens on our cluster and on our iMacs. Any help would be appreciated. Also I can attach my mdp files.

Without substantially more information, including even more (like a thorough description of what these systems are and the exact commands of what worked before), then you won't get any useful advice. -Justin Thank you TJ Mustard Email: musta...@onid.orst.edu -- Justin A.

Both ligands are being removed via FEP. As for commands they are identical as we have made a systematic script that sets up our systems.
