[gmx-users] Genion error

[‪Mohammad Roostaie‬ ‪]

Hi All, when I wanted to add ions to the system, I got this error:
Fatal error:No line with moleculetype 'SOL' found the [ molecules ] section of file 'gr.top'For more information and tips for troubleshooting, please check the GROMACSwebsite at http://www.gromacs.org/Documentation/Errors
However, there is 'SOL' molecule type in the [ molecules ] section of the topology file. Can you please help me to solve this problem?
Thanks,Mohammad
