Hi Hongtao, ChimeraX doesn't have a tool to do this, but you can use the "Flatten Icosahedron" tool in Chimera to make this kind of image for icosahedral viral capsids: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/flatten/flatten.ht...> It works on the low-resolution chain surfaces generated by the Chimera tool "Multiscale Models" from the atomic structure of the asymmetric unit -- not the EM map surface, as far as I know, and only for a specific orientation of icosahedral symmetry. I have seen flattened images of map surfaces in papers, but suspect that they were made with some other program (not Chimera or ChimeraX). Best, Elaine ----- Elaine C.

Hi there, Could you show me how to flatten a cryoEM map in chimera just like the attachment? My map has several subunits but with C1 symmetry. Thanks, Hongtao <Image.png>
