So, to be clear, we have video data of every run for each of our subjects. There is a part of the standard, at least as originally published in Nature, that seems to suggest that it is permissible to place non-BIDS-compliant data in the standard directories wherever common sense would suggest it would go, and hope a standard will come out some day. Is that correct? "For example one may want to include eye tracking data in a vendor specific format that is not covered by this standard. The most sensible place to put it is next to the continuous recording file with the same naming scheme but different extensions. "
