[gmx-users] grompp - Invalid command line argument

[Lara Bunte]

Hi

I used the command 


grompp -f em.mdp -p topol.top -c solvated.gro -o em.tpr

and got the error

Source code file: /home/adrian/src/gromacs-4.5.5/src/gmxlib/statutil.c, line: 819

Invalid command line argument:
em.tpr


What is the problem here?

Greetings
Lara
