Widget Connectivity
Widget Connectivity
Source code: https://github.com/the-virtual-brain/tvb-widgets
This is part of a Pypi release: https://pypi.org/project/tvb-widgets/
tvb-widgets is also already installed in the official image released for EBRAINS lab, where you can test it directly.
Purpose
Jupyter lab widget for visualizing or do operations on a connectivity
Visualization:
- in 2D can visualize weights or tracts matrixes;
- in 3D can visualize regions and their respective edges
Operations:
- remove selected nodes from a connectivity, results in a new connectivity containing only the nodes that were not selected;
- remove unselected nodes from a connectivity, results in a new connectivity containing only the selected nodes;
- remove unselected edges, results in a new connectivity with the same number of regions but without the edges of unselected regions;
- remove selected edges, results in a new connectivity with the same number of regions but without the edges of selected regions.
Usage:
After instantiating the widget it allows export of the currently selected connectivity:
from tvb.datatypes.connectivity import Connectivity
conn = Connectivity.from_file() # defaults to connectivy_76.zip
conn.configure()
wid = ConnectivityWidget(conn, default_active_tab='viewers') # default_active_tab can be any value between 'viewers'|'operations'|'both'
display(wid)
# ....do some operations...
# replace None in the method below with the gid of the connectivity you wish to export
# if no gid is provided it will export the connectivity currently viewed
new_connectivity = wid.get_connectivity(gid=None)
new_connectivity
