Discussion around BIDS:

Brainlife has its tool to create BIDS structure https://github.com/brainlife/abcd-spec, but MEG data hasn’t been incorporated yet

• filenames in case of multiple inputs

  • better to use task_unknown

  • don’t use run neither use neither run nor session

  • maybe use acquisition (acq)

• a BIDS validator is provided, better to run it

...

• Cross talk file and fine calibration file are in BIDS, they are in the same folder as the .fif file (see https://bids-specification.readthedocs.io/en/stable/99-appendices/06-meg-file-formats.html#cross-talk-and-fine-calibration-files MEG BIDS)

  • maybe change their name

  • Soichi added them in the meg/fif Brainlife datatype

• destination file not in BIDS, Soichi tentatively added it

  • maybe it would be better to enter directly the matrix in the destination parameter of mne.maxfilter rather than a .fif file. See how to do it.

• to test this files on BL, it’s possible to add them: see the README of the meg/fif datatype

• maybe later we can add tags in the meg/fif datatype (e.g. preprocessed, maxfilter, … see https://brainlife.io/datatype/58c33c5fe13a50849b25879b)

• add these files to a dataset to test them: see readme of neuro/meg/fif https://brainlife.io/datatype/6000737faacf9ee51fa691cb

• for example the neuro/dwi datatype)

• Create a datatype Brainstorm?

  • for now Guio used raw

  • to be discussed in another meeting
