Advanced Development Topics
Most of the Scipion graphic user interfaces (GUIs) to visualize EM objects (particles, coordinates, volumes, etc) have been developed in Java, extending Xmipp ShowJ and Particle Picker. Implementation details are available here.
Scipion from the command line
There are many things you can do with Scipion using just the command line, like running tests, starting the webserver, or opening a ShowJ viewer. Read this page to learn how.
