[Chimera-users] Movie - Display Spheres

[Elaine Meng]

Hi Jared,
First question:
It is not necessary to use a single command.  You can use
    > rep sphere [stuff]
    > rep sphere [more stuff]
and then both sets of things will be shown as spheres.  Most commands  
only affect what you specify.  (main exceptions are "show" and  
"chain" ... more on this below)

If you did want to use a single command, the proper separator for the  
specifications is a vertical bar "|" (logical OR, union) and not the  
ampersand "&" (logical AND, intersection).  For example:

    > rep sphere #0:426,431,432 | :atp

although I'm thinking this would also work (I don't know which PDB  
you're using, or I'd verify this myself):

    > rep sphere #0:426,431,432:atp

Second question:
As alluded to above, "show" displays what you specify, undisplays the  
rest.  If you don't want to undisplay the rest, use "display" instead  
of "show" - the rest of what you had looks correct, though. If you  
want to undisplay all atoms except those residues and ATP, first  
"~display" everything and then specify what you want to show with  
"display" either in a single command or multiple commands.
I hope this helps,
Elaine
