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 | |||

24 | |||
25 | To show/hide the Connectivity centers/edges, access the controls available in the upper-right corner: | ||

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) | ||
