Dear Justin,

The followings are the two successive commands I used:

*grompp -f justPLA.mdp -c 20LA-2layer-4chains.gro -p t-PLA.top -o
justPLA-em.tpr

mdrun -deffnm justPLa-em*


These commands would not produce the error posted previously. The error would have resulted from:

mdrun -deffnm justPLA-em.tpr

The fact that the capitalization is different and the nature of the suffix supports this conclusion. It is better to copy directly from the terminal rather than try to recreate what you did. In any case, proper invocation of the command should solve the issue. mdrun is looking for an .xvg file containing parameters for a tabulated dihedral; it needs to be named appropriately to function correctly.
