Recognizing BIDS validated datasets

Unique badges?

Action: make list of places where these could be advertised

BIDS is not yet required in journals, we could reach out to journals for this.

OpenNeuro is typically where BIDS datasets are shared.

Action: add journal level policy for BIDS validation, start at aperture and then extend to others

Community projects board

Under ‘get involved’ on homepage

Deferred to next meeting due to unclear “Topic”

Writing up BIDS usage survey into blog post

(Franklin) —> Kim

Some of the analysis code:

https://github.com/bids-standard/usage_survey

Add info from MRIQC:

June 2022: QC metrics from ~375K unique BOLD scans and ~280K T1 scans

Task definition:

Task addition for all other modalities besides fMRI
Clarification of tasks in appendix

Task addition PRs:

Anat: https://github.com/bids-standard/bids-specification/pull/1185 - merged

PET: https://github.com/bids-standard/bids-specification/pull/1196 - merged

Task clarification:

https://github.com/bids-standard/bids-specification/issues/1314 - merged

BIDS derivatives meeting

organized by OpenNeuroPET project
end of march PET BIDS derivatives
General BIDS derivatives - 3rd week of June in Copenhangen - invites to follow for all BEP leads + maintainers (‘we’ openneuro PET have some budget for this ; applying for more)

Yes or No (maybe just a question for Kim): Can we continue adding Steering Group meeting notes to the BIDS website?

https://bids.neuroimaging.io/news.html

Kim can start doing this again -

(Added by Eric) Sell BIDS merchandise on TeePublic.com?

Easy sign-up
Proceeds could to go to Wikimedia Foundation
Can I skip adding the “(c) 2019 BIDS Contributors” to the image?

https://github.com/bids-standard/bids-specification/blob/master/LICENSE

Committee appears to be agreeable with all of this

Update governance (added by Rémi):

Rémi and Eric met to talk about several things.

Ask “Does the Governance website and documentation state how it itself should be amended?”
Propose governance for an Advisory Group members’ (lead of merged BEP) commitment:
- Cannot ask them to commit for life
- maybe 2 year minimum plus designating a successor, or some such thing
Draft email for consent of completed BEP leads for them to be part of the Advisory group or to nominate someone(s) else

Notes

Present: Robert Oostenveld, Guiomar Niso, Eric Earl (visiting maintainer), Yaroslav Halchenko, Kim Ray

Guest: invite Chris Rorden

NOTES from Chris Rorden:

BEPs are done by experts, but implementations are not done by experts

BEPs document examples, but are not clear enough in implementation details (to entry level users).
Shows unit testing for converting/translating metadata, requires test datasets and correct outputs

Terminology differs e.g. between Siemens and Philips

PET example where dicom standards were not used for BIDS
http://www.oneukrainian.com/tmp/DICOMfields.txt has rough grep for descriptions of DICOMs fields matching. Some match some not.

Suggests possibly reaching out to the tool experts/manufacturers to better implement BEPs from start to end.

Liaisons have been responsive on neurostars (Phillip Clinical Scientists UK Matthew Clemence [github drmclem] Mayo Sandeep Ganji [github sandeepganji])

We have a statement to align BIDS with current standards and vocabularies

Yarik could not locate it…

SOLUTION:

We cannot assume dcm2nii will fix all of our data conversions.

Reach out to developers for more input on BEPs before they are approved

Provide empty header files for examples of data

Would be great to have example datasets with sourcedata/ and code/ and README.md provided to describe HOW data was converted/translated

Additional expectations for BEPS before they are approved

advise each BEP to reach out to manufacturers to make them aware of the standardization ongoing, see the BEP, possibly provide feedback and even may be align metadata/terminology

Consider/formalize a common principle to choose DICOM fields naming in favor of adding new names.
