MEG-BIDS validator

Hi @jasmainak,

I copy this here so we can keep track:

The fields that should be checked are:

*Sidecar JSON document (_meg.json)**

Manufacturer	OPTIONAL. Manufacturer of the MEG system ("CTF", "Elekta/Neuromag", "4D/BTi", "KIT/Yokogawa", "ITAB", "KRISS", "Other")

ManufacturersModelName	OPTIONAL. Manufacturer’s designation of the MEG scanner model (e.g. "CTF-275"). See Appendix VII with preferred names

*Coordinate System JSON document (_coordsystem.json)**

MEGCoordinateSystem	REQUIRED. Defines the coordinate system for the MEG sensors. See Appendix VIII: preferred names of Coordinate systems. If "Other", provide definition of the coordinate system in  [MEGCoordinateSystemDescription].

HeadCoilCoordinateSystem	OPTIONAL. Defines the coordinate system for the coils. See Appendix VIII: preferred names of Coordinate systems. If "Other", provide definition of the coordinate system in  HeadCoilCoordinateSystemDescription.

DigitizedHeadPointsCoordinateSystem	OPTIONAL. Defines the coordinate system for the digitized head points. See Appendix VIII: preferred names of Coordinate systems. If "Other", provide definition of the coordinate system in  DigitizedHeadPointsCoordinateSystemDescription.

AnatomicalLandmarkCoordinateSystem	OPTIONAL. Defines the coordinate system for the anatomical landmarks. See Appendix VIII: preferred names of Coordinate systems. If "Other", provide definition of the coordinate system in  AnatomicalLandmarkCoordinateSystemDescription.

*Channels description table (_channels.tsv)**

Thanks @guiomar

Hi!

I'm not sure the acq_date is being checked properly in the validator. "Datetime should be expressed in the following format 2009-06-15T13:45:30"

Cheers,

Could you open a new issue with more details?

[guiomar]

Yes :)

[guiomar]

461

[jasmainak]

hmm ... there were two things mentioned in this issue but one was moved to #461 and the other was not. Perhaps we should reopen this?

@chrisfilo if you label this as MEG, I could perhaps tackle this in the coming days as I have more time now

[chrisgorgo]

Done! Looking forward!

[sappelhoff]

@jasmainak can we close this?

[jasmainak]

sure feel free to close
