MNE-BIDS writes the emptyroom recordings in a separate subject, called sub-emptyroom with separate subfolders for each recording session based on date, like it is described in the BIDS Specification here.
However, the BIDS specification describes a second option, where each individual’s emptyroom recording is saved within the same session as the other data (as shown here).
This is perhaps a more intuitive way of saving the emptyroom data and in some cases it would be preferred.
I couldn’t find any sign that this option is supported in MNE-BIDS, but is there a way of achieveing this with the current version?
In this case would MNE-BIDS-Pipeline still be able to find the emptyroom recording or throw and error that it is missing?
