Here's how bad channel data is stored in the COINS DB:
Each scan session is stored as a row in the mrs_scan_sessions table.
Multiple scan series may be associated with each scan, and are stored in the mrs_series table.
Scan metadata categories like bad channels are stored in the mrs_scan_data_types table.
Series are associated with many metadata categories the mrs_series_data table
(which contains a series_id, a scan_data_type_id and a value).
Exporting this data through our more modern API would result in the following format:
[
{
"scanId": 1234,
"series": [
{
"seriesId": 2345,
"seriesData": [
{
"dataTypeId": 7,
"dataType": {
"label": "bad channel"
},
"value": 21
}
]
}
],
"ursi": M87100000,
"scanDate": "01/11/1993"
}
]
