Hi,
I am new to DataWarrior, and I was wondering if there is any way that it can predict the total charge of the compound or display protonated state?
Thank you.

You could count the number of basic and acidic atoms, which uses a simple rule base algorithm. If you need more, you would need the capka.jar plugin (and a license for it) from ChemAxon, which DataWarrior can use to calculate pKa-values. With that you could create protonation states for any given pH value.
