I am running NAMD simulation in AMBER ff and eventually I want to make
an index file excluding water and ion molecules in VMD.

The problem is that selecting RESNAME NA+ CL- always throws en error. I
guess VMD does not like "+" and "-" signs. I`ve tried to mask them with
\\, {}, (), "", '' though it did not help.

Does anyone know how to make a selection of resname Cl- and Na+ in VMD?

Thank you.
