Discussion on MEG and EEG input formats

• EEG datatype in Brainlife: https://brainlife.io/datatype/5ddf1381936ca39318c5f045

• MEG datatype in Brainlife: https://brainlife.io/datatype/5dcecaffc4ae284155298383 (everything is marked “optional” because we can’t predict if a .fif file or a .ctf file will be used, but a datatype tag “fif” or “ctf” is added in addition to the datatype MEG)

...

Comment fromGEORGE Nathalie: please also consider the hdf5 format as possible format (https://fr.wikipedia.org/wiki/Hierarchical_Data_Format;https://www.neonscience.org/resources/learning-hub/tutorials/about-hdf5), it is already in Brainstorm (to check).

What datatypes? If the code is in Matlab or Python, the datatype may change (to be discussed during another meeting).

Questions for next meetings

for datatype meeting

• in https://brainlife.io/datatype/6000737faacf9ee51fa691cb, do we add calibration files such as a fine_calibration_file.dat and a crosstalk_compensation_file.fif? These files are used in the function mne.preprocessing.maxwell_filter and in mne.preprocessing.find_bad_channels_maxwell.

for meeting with Alex

• How much does MNE rely on the fif file format. Does it make sense to have data readers in all formats, and handle everything in fif internally? Is there a special case for the ctf .ds format? Question asked to Richard Höchenberger: MNE relies on .fif internally.

• Head position alignment: before, after, independently of Maxfilter?

Discussion with Aina Puce following this meeting

25 Jan 2021

• Question of creating “data types” for different “data formats” (vendors) and different “types of data” (EEG, MEG, EOG… covariance matrix, calibration file, position file, freesurfer segmentation…)
