The error message says your Amira file does not contain BoundingBox in the header. That line tells ChimeraX the size of the 3D image data in the file. I suspect it means your Amira file does not contain 3D image data (instead it might have segmentation surfaces or some other Amira objects). The Chimera Amira reader only handles 3d image data. Tom
