As you may know ShowJ is our default viewer for most of Scipion objects and Particle Picker allows us to pick particles either manually or automatically, or visualize coordinates . Scipion source packages related to ShowJ and Particle Picking include:

  • xmipp.jni : Contains Java bindings with C++ code

  • xmipp.viewer.models : Contains the different table models used to display data in ShowJ

  • xmipp.viewer.windows : Contains ShowJ main frame and associated dialogs.

  • xmipp.viewer.scipion : Contains Scipion extensions of Metadata, GalleryData and GalleryJFrame classes

  • xmipp.viewer.particlepicker: Contains base classes for particle picking: frame, canvas, micrograph, particles dialog, etc.

  • xmipp.viewer.particlepicker.training: Contains supervised picker implementation

  • xmipp.viewer.particlepicker.tiltpair: Contains tilt pair picker implementation

xmipp.viewer.particlepicker.training and xmipp.viewer.particlepicker.tiltpair packages in turn contain model and gui packages with data model and windows respectively

In the following class diagram we display ShowJ main classes and its relations:

Base classes ParticlePicker, ParticlePickerJFrame, ParticlePickerCanvas, etc, are extended to implement supervised and tilt pair picker. Images are loaded using ImagePlusLoader and displayed using XmippImageWindow, as in ShowJ.

ShowJ and Particle Picker use sockets to communicate with Scipion. There are a number of operations that require this functionality: creating subsets, registering coordinates, executing object commands, etc. The port used for communication it is specified as an input param. In Scipion, these sockets are implemented in pyworkflow/em/showj.py and pyworkflow/gui/project/project.py. In java all the operations that involve sockets use runCommand method from XmippWindowUtil class.
