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.
Moreover, to ensure that the head movements of the subject are not too important, the “rp *.txt” file provided by SPM after the Realign step (see fMRI Preprocessing pipelines>Realign menu) can be displayed using the following script: CREx_fMRI_DoRealgnFigure
The figure below provides an overview of figures generated by this code for a given subject.
