Strictly speaking, yes, but practically speaking, this is rarely done. The EPI must be volume registered to the anatomical used to generate the surface. Depending on how the surface was generated, some surface translations/flips might be necessary to align the surface with the volume.
Typically, statistical output maps are overlaid on the surface (e.g., activity doing task A over baseline) -- not raw EPI. But there are methods for animating the rendering of metric columns, if they are captured at different timepoints. I have not done it, but others have done so. No promises on how easy it is. > Hi, > I couldn't find this in the documentation and among the tutorials so > I'm giving this a shot here.
