Respiration (resp)

Following the guidelines from BIDS v1.10.0, we propose the following additional requirements for respiratory data.

Modality specific data SHOULD be split into modality specific files carrying the modality-label. Modality label for respiration data is resp and resp specific data files would be organized as follows

physio/
├─ sub-01_ses-1_task-TaskName_recording-ecg_physio.json
├─ sub-01_ses-1_task-TaskName_recording-resp_physio.tsv.gz

Column names in the resp data files MUST be resp for experiments involving single recordings, or resp1, resp2, resp3, … for experiments involving different types of respiratory measurements like chest volume, abdominal volume, pressure, etc.

These fields MUST be included in the JSON sidecar file: <matches>_recording-resp_physio.json

Additional Metadata Fields

Table 1: Required SCR-Specific JSON Fields

Key	Description	Data Type	Possible Values
SensorType	Type of sensors used for the respiratory measurements	Text	Bellows, Cushion, Strain Gauges,…
Placement	Placement of the respiratory measurement device	Text	Chest

In case of compressed tabular files (like `.tsv.gz`) column names MUST NOT be included.
