Hi Pranav, The image in my last email was created useing the 5 commands I listed in that email. The main drawback is it gives a 360 view from a point at the middle of the map looking out. So it can be used to see what the inside of a virus capsid looks like, but not the outside. My other suggestion about combining strips of a thousand images during a rotation is what would allow getting an outside 360 degree view. Tom

Love it! Thanks Tom, this might just work. WOuld you be happy to share the script you used to generate that stretched out view?

Hi Pranav,
I guess you mean you want to save a 360 degree projection image of your colored map? There is nothing quite like that in ChimeraX. If you want a 360 view from the center of the map you can get that with "camera 360" after positioning the view point in the middle of the map. For example
open 1080 from emdb color cylindrical #1 palette redblue move z 350 turn x 90 center #1 camera 360
There is also command volume unroll that can unroll a cylindrical map. But it does not preserve coloring. And there was a flatten icosahedron capability that worked with atomic models in Chimera that is not in ChimeraX.

For what you want you could spin the model around 360 degrees recording images each 0.2 degree, then have a script take the center column of pixels from each image and lay those columns side-by-side in a single image 1800 pixels wide.

hi Team, This is potentially a left-of-center question, but is there a way I could generate a mercator projection of an MRC volume that I have colored by zone? I am happy to code this up in the chimerax python environment, but I am not sure how I could access the voxel colour information before projecting the volume.
