Hi Martin,

Try the following:

color tv_red, resn asp+glu
color tv_red, resn asp or resn glu

Dear all
What is the selection syntax to select all GLU and ASP residues within an object?

I'm trying it the way its written on the wiki:
remove resn hoh    # remove water
h_add              # add hydrogens
as surface
color grey90
color slate, resn lys       # lysines in light blue
color paleyellow, resn cys  # cysteines in light yellow
color tv_red, (resn asp or(resn glu))  # aspartic and glutamic acid in light red

but, the selection kind of does not work for me (I'm assuming the operator for the logical AND is 'and').
What is it that I need to do differently?

Kind regards
