I am trying to perform simulation of my protein-ligand complex system following Gromacs Protein-Ligand complex tutorial , so during the NVT equilibration using the command

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

iI encountered an error

"Assertion failed:

Condition: ip.constr.dA > 0

We should only have positive constraint lengths here"

i am using gmx version 2022

enclosing nvt.mdp input file

how to solve this error ?
