RE: [PyMOL] Coloring gradient

2004-11-03 Thread Peter Teriete
Thanks to all for the help so far. I'm getting there, but am currently
pondering
about the definition of the palette_dict. I wanted to add a color gradient
such
as grey_yellow, as the green_yellow didn't work as well as I was hoping for.
I'm not entirely sure what the color codes refer to.

 i.e.

  'yellow_blue'   : ('c',3,  0, 83),
  'blue_yellow'   : ('c',3, 83,  0), 
 
What do the parameters 'c', 3, 0 and 83 refer to, respectively? And is there
a 
quick way to find the correct numbers matching a certain color for a
customized
gradient? Thanks for any further help.

Peter

count is the operator you're looking for:

spectrum count, green_yellow, selection=50-100/

 I think I can help you except for one part.  In short you
 want the 'spectrum' command.  For example, you can color a 
 chain R, based on the b-factor with the command:
 
 spectrum b, green_yellow, chain R
 
 The problem is that you must color based on a numeric value
 that each atom has associated.  So let's say you want to 
 color a helix from residue index 300-400.  I tried:
 
 spectrum resi, green_yellow, resi 300-400 spectrum
 resi_number, green_yellow, resi 300-400
 
 ...and several other variations without success.  Somebody
 out there might no the answer to this problem.

Will this work for what you want to do?

spectrum palette=green_yellow
