29 === Operations: ===
30
31 - remove selected nodes from a connectivity, results in a new connectivity containing only the nodes that were not selected;
32
33 - remove unselected nodes from a connectivity, results in a new connectivity containing only the selected nodes;
34
35 - remove unselected edges, results in a new connectivity with the same number of regions but without the edges of unselected regions;
36
37 - remove selected edges,  results in a new connectivity with the same number of regions but without the edges of selected regions.

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