To all you colouring aficionados, I've updated the color_b.py script on my web page to include Mark Wall's addition of user-defined, 3-colour, gradients. Now you can type on the command line something like:
color_b selection, gradient=user, user_rgb=(0.,.3,1.,.8,.8,.8,1.,.8,0.) to get colours that range from a light blue (0, .3, 1) , through grey (.8, .8, .8) to orange (1, 0.8, 0). Or you can use integer values between 0 and 255 like so: color_b selection, gradient=user, user_rgb=(0.,77,255,204,204,204,255,204,0.) If any one value is larger than 1, then it is assumed that all values are between 0 and 255. You can find it in: http://pldserver1.biochem.queensu.ca/~rlc/work/pymol/ Cheers, Rob -- Robert L.
