		10	== Purpose ==
		11
		12	Jupyter lab widget for visualizing or do operations on a connectivity
		13

		15	=== Visualization: ===
		16
		17	- in 2D can visualize weights or tracts matrixes;

		20
		21	- in 3D can visualize regions and their respective edges

		25
		26
		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.
		36
		37
		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	conn = Connectivity.from_file() # defaults to connectivy_76.zip
		47	conn.configure()
		48
		49	wid = ConnectivityWidget(conn, default_active_tab='viewers') # default_active_tab can be any value between 'viewers'\|'operations'\|'both'
		50
		51	display(wid)
		52	# ....do some operations...
		53	# replace None in the method below with the gid of the connectivity you wish to export
		54	# if no gid is provided it will export the connectivity currently viewed
		55
		56	new_connectivity = wid.get_connectivity(gid=None)
		57	new_connectivity
		58	{{/code}}
