ConnectivityPlot

Plot estimated connectivity / directed or undirected information flow between 3d regions of interest (ROIs) in brain source space.

This node accepts a connectivity measure, estimated by one of the nodes in the connectivity category and plots the most recent time point in the data. The rendering is done as a graph of spherical nodes for the regions, connected by conical edges according to the flow direction and strength. The data is expected to have two space axes to store the all-to-all connectivity between ROIs. This node also provides keyboard shortcuts for changing the color scale (+ and -). Note that this plotter is not meant for offline review of a whole dataset. Version 0.9.7

Ports/Properties

data

Data to display.

  • verbose name: Data
  • default value: None
  • port type: DataPort
  • value type: Packet (can be None)
  • data direction: INOUT

stream

Name of stream to display. Wildcards are supported.

  • verbose name: Stream To Display
  • default value: None
  • port type: StringPort
  • value type: str (can be None)

stream_name

  • verbose name: Stream Name
  • default value: None
  • port type: AliasPort
  • value type: str (can be None)

headmodel

Headmodel file to use. If not given, this node will look in the 'headmodel' property of the data, which would usually be written by the initial sourc estimation node in your pipeline.

  • verbose name: Override Headmodel Filename
  • default value: None
  • port type: StringPort
  • value type: str (can be None)

colormap

Colormap to use for plotting activity.

  • verbose name: Activity Colormap
  • default value: Bipolar
  • port type: EnumPort
  • value type: str (can be None)

title

Title of the plot. This is the title of the plot window.

  • verbose name: Title Of Plot Window
  • default value: Time series view
  • port type: StringPort
  • value type: str (can be None)

initial_dims

Initial position of the window on the monitor. This is given in pixels, and is expressed as [x, y, width, height]. If x, y are both set to 0, the window will appear in the top left corner of the screen.

  • verbose name: Initial Window Position
  • default value: [50, 50, 700, 500]
  • port type: ListPort
  • value type: list (can be None)

set_breakpoint

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

  • verbose name: Set Breakpoint (Debug Only)
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

metadata

User-definable meta-data associated with the node. Usually reserved for technical purposes.

  • verbose name: Metadata
  • default value: {}
  • port type: DictPort
  • value type: dict (can be None)
