<div class="">For small volumes you can use the Dynamo command "dcoordinates", I wrote a small walkthrough for this:</div>

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.</div>
