Hi I create a file pr.mdp for equilibrating the water around my molecule and used after that the command
grompp -f pr.mdp -p topol.top -c em.gro -o pr.tpr And I got tthe error: Fatal error: Group protein not found in index file. Group names must match either [moleculetype] names or custom index group names,in which case you must supply an index file to the '-n' option of grompp. Could you explain that error to me please? How to fix it?
