There is conflicting information as to whether maxfiltered MEG data should be represented as as raw (with proc- or as derivatives
The main specification now contains
After applying the MaxFilter pre-processing tool, files should be renamed with the corresponding label (e.g. proc-sss) and placed into a derivatives subfolder.
but also
SoftwareFilters | REQUIRED. List of temporal and/or spatial software filters applied, or ideally key:value pairs of pre-applied software filters and their parameter values: e.g., {"SSS": {"frame": "head", "badlimit": 7}} ...
where the last relates to the meg.json of the raw data. This is in line with "8.4.1 MEG recording data" which gives the example that "proc-xxx" with xxx=sss, tsss, trans, quat, mc, etcetera, can be used for a maxfiltered meg dataset.
