Hi Aaron, Greg Pintilie who wrote Segger is going to move it from SourceForge to GitHub hopefully in the next few weeks. Then I will do an initial port from the current Chimera 1 code to ChimeraX that will be just a command based interface. Optimistically I might have that a month from now, more likely 3 months from now. It is going to take a few years to get ChimeraX doing most of the things Chimera 1 does now, on top of the new features we are constantly adding to ChimeraX. Tom

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

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.

Dear x-users,

I've tried to open x3d files using recent Mac and Linux dailies, but without any success. This would be useful as a way to view maps colored in Chimera 1 & Segger. I take it from docs/user/commands/open.html that the following usage should be supported:

open ~/Desktop/color.x3d format x3d

but I only get the error below. Any suggestions would be welcome.

Aaron
