ds000117 MEG channels.tsv should very probably be in the meg subfolder

[Remi-Gau]

The spec is pretty clear about this:

https://bids-specification.readthedocs.io/en/latest/04-modality-specific-files/02-magnetoencephalography.html#channels-description-_channelstsv

evidence:
https://github.com/bids-standard/bids-examples/tree/master/ds000117/sub-01/ses-meg

Will raise an issue in the validator regarding this.

inheritance principle says it's okay: https://bids-specification.readthedocs.io/en/latest/02-common-principles.html#the-inheritance-principle

[sappelhoff]

right ... the inheritance principle says:

Any metadata file (such as .json, .bvec or .tsv) MAY be defined at any directory level.
