Dear GMX experts, I am trying to model a protein building its ligand but am having trouble generating the ions before I proceed with the energy minimization. I have been following the Protein-Ligand tutorial and able to make the commands run non-interactively using MPI. I tried following http://www.gromacs.org/Documentation/How-tos/Using_Commands_in_Scripts to no avail. Currently, I am using Gromacs/2016.4.d with intel/2018.5.274 and impi same version. I tried using Gromacs/2019.1. My other option is version 5.0.4 Does anyone have a suggestion how to run genion non-interactively? Below are the line from my slurm file and the outputs it generated.

MPI builds have problems reading from streams like this. No GROMACS tool benefits from MPI except mdrun, so use a non-MPI gmx binary for everything else.
