I think the program rivem (radial interpretation of virus electron-density map) will allow you to do this.

Subject: [EXTERNAL] [3dem] Surface projection maps.

Hi all

I would like to do something which I'm hoping that someone else has done before, or at least something similar and might have a solution to share.

I have some raw tomograms of spherical-ish viral particles and I would like to create a flattened (projected) 2D image of the surface of a single virion. I'm thinking that it would be sort of like making a world map using the Mercator projection, i.e. projecting a sphere onto a cylinder and "rolling out" the cylinder. Ideally there would be a way to average several pixels in each direction to enhance the contrast in the tomogram.

Has anyone seen something like this done in a publication or has even done something like this themselves?

Best wishes,
