5 -== Purpose ==
6 -
7 -It is a Jupyter widget intended for visualization of the 3D Head data available for a patient:
8 -
9 -* surfaces of different types (cortex, face, skull, etc)
10 -* connectivity region centers
11 -* sensors locations (SEEG, MEG, EEG)
12 -
13 -== Inputs ==
14 -
15 -It supports the above data in the form of their corresponding TVB datatypes:
16 -
17 -* Surface (CorticalSurface, FaceSurface, etc)
18 -* Connectivity
19 -* Sensors (SensorsInternal, SensorsMEG, SensorsEEG)
20 -
21 -== Installation ==
22 -
23 -(% class="box" %)
24 -(((
25 -pip install tvb-widgets
26 -)))
27 -
28 -== API usage ==
29 -
30 -We need to first import the widget __API from tvbwidgets__// //package, together with the __TVB API __and the __display__ function:
31 -
32 -(% class="box" %)
33 -(((
34 -import tvbwidgets.api as api
35 -
36 -from tvb.simulator.lab import *
37 -
38 -from IPython.core.display_functions import display
39 -)))
40 -
41 -Then, there are 2 options to work with the widget:
42 -
43 -1. Use a file browser to load the data and automatically display it
44 -1. Use directly the API to load the data and display it
45 -
46 -
47 -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:
48 -
49 -(% class="box" %)
50 -(((
51 -widget = api.HeadBrowser()
52 -display(widget)
53 -)))
54 -
55 -
56 -For the second option, the API is described below:
57 -
58 -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:
59 -
60 -(% class="box" %)
61 -(((
62 -widget = api.HeadWidget()
63 -
64 -face = surfaces.FaceSurface().from_file()
65 -
66 -face.configure()
67 -
68 -widget.add_datatype(face)
69 -display(widget)
70 -)))

76 -Next, we can continue adding other datatypes to this widget, by calling //**add_datatype**// multiple times. A maximum of 10 datatypes are supported by this widget.
77 -
78 -The **Config** object can be used to tweak the display options for each datatype.
79 -
80 -In the code below, we add a **Connectivity** and SEEG **Sensors:**
81 -
82 -(% class="box" %)
83 -(((
84 -conn = connectivity.Connectivity().from_file()
85 -
86 -conn.configure()

102 -We can also provide a **RegionMapping** to be used as colormap for a surface:

104 -(% class="box" %)
105 -(((
106 -reg_map = region_mapping.RegionMapping.from_file()
