Virtual Brain integrated EBRAINS tools and workflows
The Virtual Brain (TVB) is an open source platform for constructing and simulating personalised brain network models. It is available as standalone version from this website
End-to-end workflow for creating personalised brain models to running multi-scale brain simulations with The Virtual Brain are now available as integrated software solutions on the EBRAINS cloud.
• Find TVB tools and data via the Knowledge Graph
• Use TVB workflows via the Collaboratory
• Run TVB workflows in the EBRAINS Cloud or on HPC backend
Integrated TVB workflows on EBRAINS enable the processing of large cohort data sets - solving the problem of small numbers preventing generalizable results, a precondition for clinical translation.

A TVB User Story From MRI to personalized brain simulation
Here we explain step by step how to use The Virtual Brain (TVB) tools for end-to-end personalized brain simulation. We start by finding shared MRI data using KnowledgeGraph, create a brain model from extracted connectomes using TVB pipeline, and simulate neural activity using TVB brain network model simulators. We will use Jupyter notebooks on EBRAINS Collab platforms for frontend operations and supercomputers in the backend for intensive number crunching.
