Purpose

It is a Jupyter widget intended for the visualization of brain signals represented as time series.

Inputs

It supports time series inputs of two types:

• TVB TimeSeries datatype
• Numpy arrays

The widget supports 2-, 3-, and 4-dimensional arrays. In all three cases, there is a fixed shape that the TimeSeries widget expects:

• for 2D: (no_timepoints, no_channels)
• for 3D: (no_timepoints, state_variable/mode, no_channels)
• for 4D: (no_timepoints, state_variable, no_channels, mode)

* Note that the TVB TimeSeries datatype is always is always 4D and already has the expected shape.

Requirements and installation

Before installing the tvb-widgets library containing the TimeSeries widget, the following python libraries and  Jupyter Notebook extensions should be installed:

• Libraries:
  • ipympl

• Extensions:* 

  jupyter labextension install @jupyter-widgets/jupyterlab-manager

  • jupyter labextension install jupyter-matplotlib

Then, to install the tvb-widgets library just type:
