Scipion EM Classes¶
Electron microscopy image processing follows a common workflow. Protocols for the different image processing steps are represented below (click on image to see full size image).
Fig. 1. General EM protocols hierarchy
Data objects processed on these protocols are the following:

Each package provides its own implementation of the different protocols, e.g.: Xmipp.

Note: These diagrams were generated using pyreverse in the following way:
pyreverse -A -o png -p protocol pyworkflow/em/protocol* --only-classnames
- -A: looks for all ancestors in all classes
- -o : specifies output format
- -p: generates output files using project name provided
In this example we used `pyworkflow/em/protocol*` as input to generate protocols hierarchy only.
If you get a “No such file or directory” error, you might need to install graphviz
`sudo apt-get install graphviz`
