11 -This is a Jupyter Lab extension that offers graphical support for TVB and VBI workflows. It is already available in the EBRAINS Lab and it allows users to configure and execute TVB simulations and VBI inference workflows directly from a GUI, while drastically reducing the complexity of configuring them inside a Jupyter Lab notebook.
