[gmx-users] error with genion

[shahab shariati]

Dear gromacs users

I add 4 Cl ions to my system using genion:

genion -s ions.tpr -o system.gro -p topol.top -nn 4 -nname CL -nq -1

I encountered with following error:

No line with moleculetype 'SOL' found the [ molecules ] section of file
'topol.top'

I checked topolo.top file:

[ molecules ]
; Compound        #mols
DPPC       128
drg          4

SOL              6382

How to resolve this problem.

Any help will highly appreciated.
