This data mode is now supported in RELION-4 and IMOD, and is interesting to save storage in cryo-ET and subtomogram averaging workflows. Would it be possible to implement support for reading and writing this MRC data mode in ChimeraX? Thank you! Best wishes, -- Ricardo Diogo Righetto" enhancement closed moderate Volume Data fixed Elaine Meng all ChimeraX
