Dear FS experts,
I would like to compute within-subject correlation between two modalities based on vertexwise maps in fsaverage space. I wonder whether I have to smooth the normalized surface-based maps before computing vertexwise within-subject correlation?
I have noted that smoothing surface maps before computing correlation increases the output correlation value.
Thanks for your lights.
Best, Matthieu
