[gmx-users] Grompp not producing tpr files

[Israel Estrada]

Hello users,


I'm running into problems trying to grompp; I'm using the command


gmx grompp -f ions.mdp -c etc_box.gro  -o ions.tpr -p topol.top


and the process shows no error messages, but output files are not being generated. I'm running this on a small molecule, about 20 atoms, with the hopes that I can modify OPLS parameters as needed. I'm sure the problem is related to an error in the topology files, but I don't know how or if I can fix this.


Any help would be greatly appreciated, thank you!
