	1	+== Widget Connectivity ==
	2	+
	3	+Source code: [[https:~~/~~/github.com/the-virtual-brain/tvb-widgets>>url:https://github.com/the-virtual-brain/tvb-widgets]]
	4	+
	5	+This is part of a Pypi release: [[https:~~/~~/pypi.org/project/tvb-widgets/>>url:https://pypi.org/project/tvb-widgets/]]
	6	+
	7	+//**tvb-widgets**// is also already installed in the official image released for EBRAINS lab, where you can test it directly.
	8	+
	9	+
	10	+== Purpose ==
	11	+
	12	+Jupyter lab widgets for visualizing or do operations on a connectivity
	13	+
	14	+
	15	+=== 1. ConnectivityWidget ===
	16	+
	17	+==== Visualization: ====
	18	+
	19	+ - in 2D can visualize weights or tracts matrixes;
	20	+
	21	+[[image:conn2d.png||height="741" width="1700"]]
	22	+
	23	+ - in 3D can visualize regions and their respective edges
	24	+
	25	+==== [[image:conn3d.png||height="688" width="1700"]] ====
	26	+
	27	+To show/hide the Connectivity centers/edges, access the controls available in the upper-right corner:
	28	+
	29	+[[image:visible.png||height="543" width="500"]]
	30	+
	31	+==== Operations: ====
	32	+
	33	+ - remove selected nodes from a connectivity, results in a new connectivity containing only the nodes that were not selected;
	34	+
	35	+ - remove unselected nodes from a connectivity, results in a new connectivity containing only the selected nodes;
	36	+
	37	+ - remove unselected edges, results in a new connectivity with the same number of regions but without the edges of unselected regions;
	38	+
	39	+ - remove selected edges,  results in a new connectivity with the same number of regions but without the edges of selected regions.
	40	+
	41	+
	42	+==== Usage: ====
	43	+
	44	+After instantiating the widget it allows export of the currently selected connectivity:
	45	+
	46	+{{code language="python"}}
	47	+from tvbwidgets.api import ConnectivityWidget
	48	+from tvb.datatypes.connectivity import Connectivity
	49	+
	50	+conn = Connectivity.from_file() # defaults to connectivy_76.zip
	51	+conn.configure()
	52	+
	53	+wid = ConnectivityWidget(conn, default_active_tab='viewers') # default_active_tab can be any value between 'viewers'|'operations'|'both'
	54	+
	55	+display(wid)
	56	+# ....do some operations...
	57	+# replace None in the method below with the gid of the connectivity you wish to export
	58	+# if no gid is provided it will export the connectivity currently viewed
	59	+
	60	+new_connectivity = wid.get_connectivity(gid=None)
	61	+new_connectivity
	62	+{{/code}}
	63	+
