Hi Doug, I determined that SPM does create a mean volume during motion correction. My question now is how do I incorporate several functional runs (each with a different "template" mean volume from motion correction) into a registration with the anatomical. I have statistical activation maps generated based on 4 functional runs, so eventually I would like to overlay this on the anatomical volume in Freesurfer and extract information from ROIs. If I were to use one of the "template" mean volumes (say from function run 1) to conduct the registration then I would be assuming that the subject did not move across the rest of the runs.
Your thoughts are greatly appreciated.

I'm not sure what SPM uses as the motion correction template. It's probably the middle time point or the average across all time points. But it is using something. You need to find out what it is and use that. doug Palzes, Vanessa wrote: > Hi Doug, > > Thanks for your help.
