You will only need an HBP account for accessing this: [[https:~~/~~/tvb-multiscale.apps.hbp.eu/>>https://tvb-multiscale.apps.hbp.eu/]] 26 26 27 -T VB-multiscale ismade available at[[EBRAINS JupyterLab>>https://lab.ebrains.eu/]].27 +This JupyterHub installation works smoothly with HBP Collab user credentials (login only once at HBP and get access here too). We use a custom Docker Hub tvb-multiscale image as a backend, and thus a ready to use environment is available immediately, without the need of any local installation or download. This should be the ideal env for demos, presentations or even workshops with tvb-multiscale. 28 28 29 - All the user has to dois login withheir EBRAINS credentials, and start a Python consoleor a Jupyternotebook usingthekernel "EBRAINS-23.09" (or a more recent version), where TVB-multiscalean be imported(e.g., via "import tvb_multiscale").

Periodically, we will clean all changes under TVB-*-Examples folder (by redeploying the pod image), and show the original example notebooks submitted on our Github repo.

This will be efficient when the simulation jobs are very large. From our experience, with small jobs, the stage-in/out time is considerable, and then the user might be better with just a local run. Also, this deployment requires that **the user have an active CSCS personal account**.
