- Conventions: ZXZ, not standard
- Header metadata
- Supported image formats
- CTF model
- Image center convention
- Euler angles: (az,alt,φ) φ is in-plane rotation for tilted image. For untilted φ=az=in-plane rotation
- Rotation matrix:
[[cos phi,sin phi, 0],[-sin phi,cos phi,0],[0,0,1]]
[[1,0,0],[0, cos alt, sin alt],[0, -sin alt, cos alt]]
[[cos az,sin az, 0],[-sin az,cos az,0],[0,0,1]]Particle coordinate files format: box files contain x/y coordinates of the lower left corner of the box; json files contain x/y coordinates of the box center
