27 === Operations: ===
28
29 - remove selected nodes from a connectivity, results in a new connectivity containing only the nodes that were not selected;
30
31 - remove unselected nodes from a connectivity, results in a new connectivity containing only the selected nodes;
32
33 - remove unselected edges, results in a new connectivity with the same number of regions but without the edges of unselected regions;
34
35 - remove selected edges,  results in a new connectivity with the same number of regions but without the edges of selected regions.

38 === Usage: ===
39
40 After instantiating the widget it allows export of the currently selected connectivity:
41
42 {{code language="python"}}
43 from tvbwidgets.api import ConnectivityWidget
44 from tvb.datatypes.connectivity import Connectivity
45
46 import pyvista as pv
47
48
49 pv.set_jupyter_backend('pythreejs')
50
51 conn = Connectivity.from_file() # defaults to connectivy_76.zip
52 conn.configure()
53
54 wid = ConnectivityWidget(conn, default_active_tab='viewers') # default_active_tab can be any value between 'viewers'|'operations'|'both'
55
56 display(wid)
57 # ....do some operations...
58 # replace None in the method below with the gid of the connectivity you wish to export
59 # if no gid is provided it will export the connectivity currently viewed
60
61 new_connectivity = wid.get_connectivity(gid=None)
62 new_connectivity
