Interesting that you have your Ca2+ ions in the beginning of your
structure file. In this case, remove the line [ SOL ] and replace [ CA ]
with [ SOL ].
Although, changing your mdp file to have "Protein Non-Protein" is simpler.
The rationale behind is that the *groups* included for the tc-grps shall
cover all atoms.
