Adding Labels

Recent changes in Java security policy might prevent you from running VARNA.

Adding text labels: The annotations example
Java Get Powered

Different types of textual annotations can be added to a VARNA drawing:

  • A - Loop annotations: They are located in the barycenter of a loop, moving along with its bases. As for every other type of annotations, a custom font size can be specified through the color.
  • B - Helix annotations: They are marking a whole helix, moving along with its bases and located within it. For every annotation, a custom color can be specified.
  • C and D - Base annotations: Located on the side of a single base, they can be gently pushed further away to avoid a possible collision with a base number.
  • E - Static annotations: They are drawn at a fixed positions within the panel.

Lastly, substructures can be automatically annotated, as was done in this example with terminal loops using the parameter autoTerminalLoops.
