If you want to see the full VDW size of those residues, use the sphere
You can also specify any one by residue number and chain ID, for example
select :342.A z<5.0
I don't know what the issue is with your structure or what you mean by
"did not work" but perhaps the easiest way for you would be just to
select that atom (Ctrl-click in the graphics window) and then use
"sel" to specify it:
select sel z<5.0
I'm not aware of any use of PSF/DCD in Chimera except as trajectory
input. What do you mean? Writing it out?
