WebJul 5, 2024 · We have looked into this in more detail and we believe that cryosparc defines Dn as Cn around z + C2 around Y, while relion and xmipp, and maybe others, define it as Cn around z + C2 around X. Therefore, pyem 3d angles conversion is not a straightforward conversion, at least for Dn symmetries.
