Hi, I was wondering if I missed this feature in Chimera somewhere...a way to fill in nucleotide base rings/planes, this is what I mean: http://linegli.mc.vanderbilt.edu/~sabuj/1GQU_ribbons.png (using ribbons v3.2) http://linegli.mc.vanderbilt.edu/~sabuj/1GQU_vmd.png (using vmd 1.8.2) If you've ever used Ribbons you know it's a real pain to setup. I actually ended up using Chimera's selection methods to create separate pdb files for inputs into Ribbon's scripts, and it doesn't do multi-colored surfaces/transparency very well. VMD as you can see is filling in the ribose sugars (which I don't want) and is failing to fill in some of the bases. I tried recompiling it's code with some modifications but failed due to some header problems. Anyways I was wondering if this feature might be added, if it already isn't there, with the ability to choose colors for the base rings, or attribute certain colors to groups of bases, etc. Thanks, Sabuj
