These are the slides presented by Denis Engemann in the Open Science Panel discussion at the BIOMAG 2018 meeting in Philadelphia. You can find the original version on https://speakerdeck.com/dengemann/mne-hcp-pitch-biomag-2018

1. Lessons learned from processing the
Human Connectome MEG data

2. Q: Why would you care about a
Python reader for the HCP MEG data?

3. Bridging resources
• Dataset provider: make sure the data can be used
with any tool.
• Software provider: make sure the software can be
used with any dataset
• Researcher: use a baseline dataset in a most
unconstrained way. Enabling cross-toolbox, cross-
methods, cross-site comparisons

4. Example 1: validation of power envelope connectivity
Soon in
CTF Brainstorm
Hipp et al. Nat Neuro 2012
CAMCAN
HCP

5. Example 2: Benchmark against new MNE family solvers
Challenge me!

6. Example 3: compare machine learning tools

7. Challenges we solved together
• The ethics protocol may not allow sharing all
aspects of the data
• Derivative data may be stored differently from what
your tools expects (anatomy, coordinate systems)
• Knowing which information is which file and how to
get the missing bits and pieces

8. Programmatic access to HCP data

9. …/mne-hcp/auto_tutorials/index.html
Add your
example!
Run all analyses supported by MNE on HCP data

10. Add your
example!
Load the evoked responses

11. Add your
example!
Get the forward model and compute the noise covariance

12. Add your
example!
Compute the inverse solution

13. Add your
example!
Be fascinated by visual cortex activity

14. The lessons learned
• Principle of charity: there can be good reasons why
some data are not easily available.
• Work together with data providers
• Document how a data resource can be used with
your software
• Mind your community’s software eco-system
• Talk to each other!
