A pipeline for the automated coregistration of sub-millimeter resolution functional maps from brain sub-volumes was implemented and tested in a non human primate model of focal somatosensory cortical activation. Preliminary studies demonstrate an accuracy of coregistration of about 30 micrometers for structural and 100 micrometers for functional maps across separate sessions.
