I am looking at intracranial electrode recordings from some epileptic patients. The locations of the electrodes have been determined using a preoperative MRI and a postoperative CT scan. The locations are in RAS coordinates. Is there some sort of function that will allow me to translate the RAS coordinates to Talairach coordiantes? Or some sort of function that will output an anatomical label for each of the RAS coordinates?
Please let me know what I need in addition to the RAS coordinates as a .mat file. For example, do I need to install FreeSurfer? What additional files do I need?
My preference would be to do this all in Matlab.
Sincerely, Sujith
