@bdemchak @yihangx These functions have a ton of parameters. I'd recommend letting me slog through them first, before tyring to translate to py4cy. This work is still uncovering bugs in the commands implementation, for example.

This is quite a respectable job … lots of respect for tackling this.

Refresher (just in case):

When these stabilize, please add them to the API definition so py4cytoscape can sync up: https://docs.google.com/spreadsheets/d/1XLWsKxGLqcBWLzoW2y6HyAUU2jMXaEaWw7QLn3NE5nY/edit#gid=1999503690

FYI, v1.2.0 is implemented in py4cytoscape 0.0.9.

The cytoscape_version_info() function returns the API level for the py4cytoscape/rcy3 library. For example:

{'apiVersion': 'v1', 'cytoscapeVersion': '3.9.0-BETA1', 'automationAPIVersion': '1.2.0', 'py4cytoscapeVersion': '0.0.9'}
