# load extra file
LOAD
Loads a library, possibly defining new actions. More details
 
FILE
file to be loaded
=EMMIVox.cpp

This command is used to provide information on the molecules that are present in your system. More details
 
STRUCTURE
a file in pdb format containing a reference structure
=gromacs.pdb
