Dear users.

I can not execute the following command:

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

The error message that appears is:
-------------------------------------------------------------------------------------------------
Program:     gmx grompp, version 2019-beta3
Source file: src/gromacs/gmxpreprocess/grompp.cpp (line 1912)

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.

For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
----------------------------------------------------------------------------------------------------

It was not clear how to generate the restraint.gro file.
I hope everyone helps.

Kind regards.
