 When passed to [[fmriqasheet]], this function then creates a new figure and displays part of the information contained in the structure, which can be used to decide on whether or not a subject would likely introduce too much noise/bias at the group level.
+==== Usage notes ====
+Please be aware that the first argument **must** be a list of filenames; so, even for a single NIftI ([[xff - NII format|NII]]) file, a cell array must be passed in:
+<code matlab fmriquality_example4.m>% using a single NII file
+qas = fmriquality({'vols.nii'});</code>
+Also, please note that motion parameter estimation requires between one and several minutes (depending of the length of the run and whether or not robust motion estimation is employed). The **runtime also easily increases tenfold when robust temporal filtering is used**. In other words, these options are more useful and meant for situations where the fmriquality function is part of a larger script that automatically checks the quality of all incoming data instead of being used from the command line in a more interactive way!
