We conducted an fMRI study with periodic pain ratings entered by the
participant. We would like to ask which voxels correlate with a given
persons pain ratings throughout that persons scan-a within subject
correlation of a behavioral measure with our signal. How should we go about
doing this? For the sake of the example, lets say we have 10 subjects with
2 runs of 100TRís each. There were 15 pain ratings per run, per subject.
