Hi Tom,

Thanks for the explanation. You have guessed my use case exactly, regarding both the Regions / Color Density Map and the motive being to render with ambient occlusion. That would be quite handy; I and those else I know who work with EM maps rely on Segger to annotate them.

Thanks again,

Aaron

Hi Aaron,

ChimeraX is not able to read X3D, it can only write it. A mistake in the code caused it to claim it could read it and that got into the documentation. I've fixed that. I'll also make it give a clear error message instead of a traceback.

When you say view maps colored with Chimera 1 and Segger do you mean you use the Chimera 1 Segger menu entry Regions / Color Density Map, and you want to see that result in ChimeraX (probably for the nicer ambient occlusion lighting)? I'll take a look at how hard it would be to put Segger into ChimeraX.
