MRdataset parses the acquisition parameters for all modalities, subjects, sessions, and runs directly from DICOM headers. Neither does it depend on filename hierarchy nor it expects a particular file organization on disk to accommodate varied configurations in MRI datasets. Then, the parameter values are aggregated to assess protocol compliance for a neuroimaging dataset. We define a horizontal audit to be across all subjects in a given modality (compliant w.r.t a predefined protocol), whereas vertical audit checks if a single subject is compliant across all the acquired modalities
