Program:     gmx grompp, version 2018.1
Source file: src/gromacs/gmxpreprocess/grompp.cpp (line 2008)

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
