| 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, 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: | ||
| 42 | |||
| 43 | (% class="box" %) | ||
| 44 | ((( | ||
| 45 | widget = api.HeadWidget() | ||
| 46 | |||
| 47 | face = surfaces.FaceSurface().from_file() | ||
| 48 | |||
| 49 | face.configure() | ||
| 50 | |||
| 51 | widget.add_datatype(face) | ||
| 52 | display(widget) | ||
| 53 | ))) | ||

| 57 | {{/html}} | ||
| 58 | |||
| 59 | 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. | ||
| 60 | |||
| 61 | The **Config** object can be used to tweak the display options for each datatype. | ||
| 62 | |||
| 63 | In the code below, we add a **Connectivity** and SEEG **Sensors:** | ||
| 64 | |||
| 65 | (% class="box" %) | ||
| 66 | ((( | ||
| 67 | conn = connectivity.Connectivity().from_file() | ||
| 68 | |||
| 69 | conn.configure() | ||
| 70 | |||
| 71 | widget.add_datatype(conn) | ||
| 72 | |||
| 73 | |||
| 74 | seeg = sensors.SensorsInternal().from_file() | ||
| 75 | |||
| 76 | seeg.configure() | ||
| 77 | |||
| 78 | widget.add_datatype(seeg, api.HeadWidgetConfig(name='SEEG')) | ||
| 79 | ))) | ||
| 80 | |||

| 83 | {{/html}} | ||
| 84 | |||
| 85 | We can also provide a **RegionMapping** to be used as colormap for a surface: | ||
| 86 | |||
| 87 | (% class="box" %) | ||
| 88 | ((( | ||
| 89 | reg_map = region_mapping.RegionMapping.from_file() | ||
| 90 | |||
| 91 | config = api.HeadWidgetConfig(name='Cortex') | ||
| 92 | |||
| 93 | config.add_region_mapping_as_cmap(reg_map) | ||
| 94 | |||
| 95 | |||
| 96 | cortex = surfaces.CorticalSurface().from_file() | ||
| 97 | |||
| 98 | cortex.configure() | ||
| 99 | |||
| 100 | widget.add_datatype(cortex, config) | ||
| 101 | ))) | ||
