GUI widgets for EBRAINS showcases

Project description


Github Actions Status Maintainability Rating Reliability Rating Lines of Code

TheVirtualBrain - Widgets is a package with somehow generic GUI components, but developed for EBRAINS Showcases in particular.

The showcases developed in the last phase of the HBP are meant to illustrate the full potential of technical and scientific features offered by EBRAINS. Access by the end users to this showcased functionality should be as easy as possible. In order to support the usability of the showcases, as well as future EBRAINS workflows, we develop here a set of modular graphic solutions which can be easily deployed in the EBRAINS Collaboratory within the JupyterLab.

This module is also documented in EBRAINS here:

These graphic user interface components enable:

  1. Easy setup of models and region specific or cohort simulations. This includes single simulations as well as parameter explorations.
  2. Selection of Data sources and their links to models. This will exploit the backend data access functionality to be developed new in TVB.
  3. Integration of a subset of TVB analysis and visualisation tools.
  4. The GUIs must be designed to be integrated into cells in the notebooks and Jupyter notebook extension for HPC resource usage and job tracking will be also developed as independent panels.


This module is already available in EBRAINS lab, but you can also make use of it locally, in which case, execute:

jupyter labextension install @jupyter-widgets/jupyterlab-manager
jupyter labextension install jupyter-matplotlib
pip install tvb-widgets

In order to install tvb-widgets from the local repo clone, directly in a notebook, run (in the first cell):

%pip install --quiet --upgrade pip
%pip install --quiet -e ..
%pip install tvb-data

For some of our widgets, where connection to EBRAINS storage is necessary, you should setup as environment variable before launching the local Jupyter Lab instance:

export CLB_AUTH = "{Your TokenString copied from EBRAINS Collab}"

To retrieve the token string, execute in
