Your first steps
Once your access is approved, CHORUS.HIP works like any CHORUS instance. Here is what to expect the first time you sign in, and where the detail lives.
Sign in, open the workspace for your project, start a session, and launch the tools you need. The mechanics are the same everywhere on CHORUS - what is specific to the HIP is the iEEG tooling and the way data has to be prepared before it arrives.
Signing in
You sign in through your browser at thehip.app, with the EBRAINS account your accreditation is attached to. There is nothing to install.
The first time, you are asked to accept the terms of use. If you have not been through accreditation yet, start at Request access.
Where your work happens
Every project has a workspace, and everything belonging to that project lives inside it: the data, the people, the tools, the results. Workspaces are isolated from each other, so projects with different confidentiality requirements sit side by side safely.
A personal workspace is private to you. A collaborative workspace is shared with a project team, and the project's principal investigator is responsible for it - who is in it, what role each person holds, and closing it when the project ends.
For how workspaces work in full - isolation, network modes, roles and permissions - see Workspaces in the CHORUS tab.
Doing the work
Inside a workspace you open a session - your live working environment in the browser. It starts empty; you then launch the tools you need from the App Store, and each opens as a window.
Nothing is copied to your own computer while you work, and results leave only through a reviewed export.
Files you leave inside a running application are not necessarily kept once that application closes. Anything you want to keep belongs in the workspace's own data area.
The full picture is in the CHORUS tab: Sessions and Apps.
What is specific to CHORUS.HIP
Three things differ from a general CHORUS instance, and they are what the rest of this documentation covers:
- Access runs through EBRAINS. An EBRAINS account plus HIP accreditation, rather than an institutional login - see Request access.
- The tools are for intracerebral EEG and neuroimaging - Brainstorm, 3D Slicer, FreeSurfer, AnyWave and others. See Applications.
- Data arrives in the BIDS-iEEG standard, and converting it is something you do yourself - see Working with BIDS-iEEG.
What is next
If you are bringing data, start with Working with BIDS-iEEG to understand the standard, then Upload iEEG data.
If the data is already there, go to the tutorials.
If something does not behave the way you expect, FAQ & support has the common questions and how to reach the HIP support team.
