Hi Yolanda, I’m not aware of anything special about the MRC files from Chimera. It sounds like you simply don’t have a license to use the part of Amira that reads/handles MRC files, in which case you would need to contact the Amira folks about getting such a license. Can you open any MRC files in Amira, like from sources other than Chimera? Best, Elaine ---------- Elaine C.

Greetings,
I am a researcher working at the University of Helsinki (Finland) and I have used the software UCSF Chimera to process 3D CT-Scans data. I saved the process files as a single .MRC file. When I tried to open it with Amira 5.3.3 it displays the following error message:
"No valid licence found for extension Amira Microscopy Option 5.3 Please contact us". The console also says "Access denied for 'readMRCFileStack'"
I thought that Amira could read these standard .MRC files? Could it be there was an issue during the file export with Chimera?
