[Chimera-users] splitting and surfaces

Hi Arthur,
I really can’t tell what is going on.  I would just say that if you use command “vdwdefine” without specifying the model in the command, it will apply to all models.  It will not automatically use what is selected unless you enter “sel” as the specification.  Actually, don’t bother selecting for that purpose, just use a command like “vdwdefine +.01 #0.15"

“vdwdefine +0” does nothing, it adds zero to current radius.  If you want to back to defaults, command is “~vdwdefine”

As for coloring, I can’t tell what you mean by “attempted to change the color” … if you mean you used the menu Actions… Color, then I can only say to check on what the coloring is applying to, menu: Actions… Color… all options, see “Coloring applies to” on the right side of the resulting dialog.

Best,
Elaine

So I selected the entire chain of #0.16 and attempted to change the color, and again nothing happened. I can tell  it  was selected because the sequence of#0.16 is highlighted in green, and I can see parts of the green outline under its surface. I changed the vdwdefine command to have +.00, nothing happened, deleted  vdwdefine from the command line, again nothing happened, even when I tried to hide the surface.
