Hi Sumitro! In Chimera 1.5 each surface could have its own single-layer transparency. Thus you could still have multiple transparent layers overall, but only the top layer of each surface. I'm guessing the image is something like that (I don't have permission to view it). In Chimera 1.6 the choices are only either a single layer of transparency, or all transparent layers. In Chimera 1.5 if you turn off single-layer transparency for each surface, the result is the same as in Chimera 1.6 if you turn off global single-layer transparency. However, I realize that does not help, since you don't want to show all layers (it's often ugly, as you describe). I don't know if there is any way to get exactly what you had before, but in 1.6 I suggest trying this: use single-layer transparency (which is the default), make only the surface transparent, keep the ribbon opaque. If you want the ribbon to be less bold, try making it a pastel color. I am not involved in the graphics programming -- I CC'd the list since the other developers may have suggestions (and other users might find the discussion informative). I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco
Hi Elaine, thanks for the reply. I believe you exactly described what I did with this paragraph: "In Chimera 1.5 each surface could have its own single-layer transparency. Thus you could still have multiple transparent layers overall, but only the top layer of each surface. I'm guessing the image is something like that (I don't have permission to view it)." Sadly, I resorted to re-installing CHIMERA 1.5 cos even if I use pastel colours in Chimera 1.6, the effects were far from what I've got using the multiple-single layer transparency previously. Is there any plan to make the transparency setting more customisable in the future? that will be of great help! thanks! Cheers, Sum On 4 May 2012 00:18, Elaine Meng <meng@cgl.ucsf.edu> wrote:

Hi Sumitro, Sorry, I am not aware of any such plan. Maybe one of the programming experts will be able to suggest a python solution? Best, Elaine ----- Elaine C.

Hi Sumitro, It is hard to completely understand your problem without seeing an example image made with Chimera 1.5 using the technique you described. If you provide such an image we might have suggestions about how to make something very similar in the latest Chimera. The image link you send before gives permission denied. Tom
