I have different atom types in the structure, and found the easiest way to
select them by their charges. In the selection menu, I can easily select
atom types with positive charges. However, atoms with negative charges are
not selected and I get this error:

*Unable to parse this atom selection.*

I, for example, use this command in the Selected Atoms area:

*charge -0.798200*

The command window also shows:

*ERROR) syntax error*

What is the problem with the syntax?

Thank you.
