Hello Angus and Michael, It may be a function of the map display style. If I open a map from EMDB, e.g. commands: open emdbID:1024 stereo anaglyph I can clearly see the 3D effect when wearing red-cyan glasses (and red and cyan fringes with the glasses taken off) if I am showing surface or mesh isosurfaces for the map, but not if showing the diffuse cloud of the "solid" style. I attach an image of the map in surface style. I don't know if you can expect to see a 3D effect with the transparent "solid" style even with anaglyph stereo working correctly. I couldn't perceive it with that style. Tested Chimera 1.14 on Mac, and I believe that the map from EMDB is 32-bit floating point like your data. I hope this helps, Elaine ----- Elaine C.

Yes, the red and gray is normal, but you're seeing the combined channels. You need the glasses to separate the channels. Try viewing the image with the glasses that come with a 3D comic book.

Red-cyan, sorry. No, I didn't look for stereo at all, just to reproduce the condition posted that one channel appears in red and the other in gray. Is that normal?

Are you wearing red-cyan glasses to see the stereo? It doesn't work without them.

I'm confirming the problem with a different dataset (optical deconvolution in tif format). Red-green shows red and gray, green-magenta shows green and gray. This is with version 1.14 on linux. regards, Michael

I am looking at some cryo em data. When I try to view a a 3D stack of em dat with the Red-Cyan stereo setting I seem to only get Red and grayscale. The data is in 32-bit floating point and is in MRC2014 header format. I cannot figure out what I am doing wrong. Is anything obvious?
Thanks for your time. -- Angus McDonald amcdonald@boisestate.edu
