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 widget for visualizing or do operations on a connectivity
13 +
14 +
15 +=== Visualization: ===
16 +
17 + - in 2D can visualize weights or tracts matrixes;
18 +
19 +[[image:conn2d.png]]
20 +
21 + - in 3D can visualize regions and their respective edges
22 +
23 +==== [[image:conn3d.png]] ====
24 +
25 +To show/hide the Connectivity centers/edges, access the controls available in the upper-right corner:
26 +
27 +[[image:visible.png]]
28 +
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.
38 +
39 +
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
60 +{{/code}}
