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 +
