Here post your question:

Hello upon executing the command:

gmx grompp -f nvt.mdp -c em.gro -r em.gro -p topol.top -o nvt.tpr

towards equalilibration of my oligomer, the above and below error precipitates:

Fatal error:
Cannot find position restraint file restraint.gro (option -r).
From GROMACS-2018, you need to specify the position restraint coordinate files
explicitly to avoid mistakes, although you can still use the same file as you
specify for the -c option.

is this a path problem where my present em.gro is not calling each of the posre.itp restraint files?
(I do not see the posre.itp files designated in my current topol.top.)

Thanks if anyone can assist me with correcting this error:)

Hi I believe changing to zsh shell will allow the proper execution, at least it did on my end, thanks
hope this helps:)
