(a) An example reference protocol, and (b,c) compliance report for a toy neuroimaging dataset. Note that the reference protocol can either be pre-defined or inferred by searching for most frequent values for each parameter. The toy dataset has 7 modalities across 5 subjects. Subjects sub-566 and sub-879 are non-compliant w.r.t Pixel Bandwidth and Phase Encoding Direction respectively. For gradient-echo (GRE) modality, subject sub-566 has a non-compliant pixel bandwidth for sessions 6-10

(a) Example of a reference protocol.
Scanning Sequence	Echo Train Length	Phase Encoding Direction	Magnetic Field Strength	Phase Encoding Direction	Multi Slice Mode	Pixel Bandwidth	Flip Angle	MR Acquisition Type
GR	1	j	3	ROW	interleaved	350	40	2D
is3D	Phase Encoding Steps	Shim	Repetition Time	iPAT	Manufacturer	Sequence Variant	Body Part Examined	Echo Time
False	448	Standard	465	Grappa	SIEMENS	MTC_SS	BRAIN	3.73
