There are several ways of detecting problems with fMRI datasets. For summary images and times series diagnostics, we recommend you the reading of the following link: DataDiagnostics

For times series diagnostics, see also the code available here: CREx_fMRI_QA_tsdiffana

The figure below provides an overview of figures generated by this code for a given subject.
