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 ?
