Figure 6. Illustration of the variance explained in dataset 3 (n = 200) by different parameter combinations: complete set of realignment parameters [rps (complete)], realignment parameters from translation_only [rps (to)] and rotation_only [rps (ro)].

Note increasingly severe underestimation of total motion-induced variance when compared with the full parameter set including Volterra expansion ( = 100%); see text for details.
