Does anyone have an answer to this question?
Hello,
I am looking for a way to perform voxel-wise, within-subject correlations of two activation maps (in talairach space). The two existing maps reflect encoding and retrieval runs of a memory task. The idea would be to generate a correlation map across all subjects, to identify clusters where there was a positive or negative correlation between encoding and retrieval activation.
I've seen this done with SPM but not Freesurfer. Any suggestions? (Perhaps this would involve glmfit?)
Many thanks, Josh
