[gmx-users] how can I exclude the solvent from the output?

I am interested in running a simulation of a mycolic acid; the solvent is water.
However, I need to exclude the solvent from being written in the output in order to reduce the data volume.
So, after using editconf and genbox, what I did was edit the mdp file and add the following lines on the 'output control options' section:
; This selects the subset of atoms for the xtc file. You can =
; select multiple groups. By default all atoms will be written. =
xtc-grps = MEO
; Selection of energy groups
energygrps = MEO
I ran grompp using the input as described above. Then I did an energy minimization with mdrun, but the output I got still contains the solvent.
So obviously I did something wrong. Unfortunately searching the web didn't provide me with any answers, I know I need to edit the lines mentioned above but I am not sure how to actually edit them.
Thank you so much in advance!
