3 This is part of a Pypi release: [[https:~~/~~/pypi.org/project/tvb-widgets/>>https://pypi.org/project/tvb-widgets/]]
4
5 //**tvb-widgets**// is also already installed in the official image released for EBRAINS lab, where you can test it directly.
6
7 == Purpose ==
8
9 It is a Jupyter widget intended for visualization of the 3D Head data available for a patient:
10
11 * surfaces of different types (cortex, face, skull, etc)
12 * connectivity region centers and edges
13 * sensors locations (SEEG, MEG, EEG)
14
15 On cortical surfaces, it can also display region parcellation. 
16
17 == Inputs ==
18
19 It supports the above data in the form of their corresponding TVB datatypes:
20
21 * Surface (CorticalSurface, FaceSurface, etc)
22 * Parcellation (RegionMapping)
23 * Connectivity
24 * Sensors (SensorsInternal, SensorsMEG, SensorsEEG)
25
26 == Installation ==
27
28 (% class="box" %)
29 (((
30 pip install tvb-widgets
31 )))
32
33 == API usage ==
34
35 We need to first import the widget __API from tvbwidgets__// //package, together with the __TVB API __and the __display__ function:
36
37 (% class="box" %)
38 (((
39 import tvbwidgets.api as api
40
41 from tvb.simulator.lab import *
42
43 from IPython.core.display_functions import display
44 )))
45
46 Then, there are 2 options to work with the widget:
47
48 1. Use a file browser to load the data and automatically display it
49 1. Use directly the API to load the data and display it
50
51 For the first option, you have to run the following 2 lines of code in a notebook cell and then just use the UI controls:
52
53 (% class="box" %)
54 (((
55 widget = api.HeadBrowser()
56 display(widget)
57 )))

61 {{/html}}
62
63
64 For the second option, the API is described below:
65
66 In a new cell, we instantiate the **HeadWidget** and a **FaceSurface** datatype that we want to visualize. Using the //**add_datatype**// method we add the surface to our widget and __display__ the widget:
67
68 (% class="box" %)
69 (((
70 widget = api.HeadWidget()
71
72 face = surfaces.FaceSurface().from_file()
73
74 face.configure()
75
76 widget.add_datatype(face)
77 display(widget)
78 )))

82 {{/html}}
83
84 Next, we can continue adding other datatypes to this widget, by calling //**add_datatype**// multiple times.
85
86 In the code below, we add a **Connectivity** and SEEG **Sensors:**
87
88 (% class="box" %)
89 (((
90 conn = connectivity.Connectivity().from_file()
91
92 conn.configure()
93
94 widget.add_datatype(conn)
95
96
97 seeg = sensors.SensorsInternal().from_file()
98
99 seeg.configure()
100
101 widget.add_datatype(seeg)
102 )))

106 {{/html}}
107
108 We can also provide a **RegionMapping** to be used as parcellation for a surface:
109
110 (% class="box" %)
111 (((
112 reg_map = region_mapping.RegionMapping.from_file()
113
114
115 cortex = surfaces.CorticalSurface().from_file()
116
117 cortex.configure()
118
119
120 widget.add_datatype(cortex, reg_map)
121
122 display(widget)
123 )))
