Hi FreeSurfer Team, I was wondering if you could provide a bit more clarification on what the "-refeventdur" flag is referring to in the mkanalysis-sess command? The description in the help screen states it should be the "duration (sec) of reference event for scaling." I am unsure what the "reference event" is. I couldn't find any additional info on the listserv, and the two examples I saw from tutorials used a value of "4" and another used a value of "16". Any clarification is greatly appreciated! Because the help for the flag is listed under the "Assume a shape" header, does it have something to do with the HRF?
Thanks so much! Tori -- Victoria J. Williams, PhD Clinical Research Fellow Interdisciplinary Brain Center Massachusetts General Hospital Harvard Medical School Department of Neurology 149 13th Street Charlestown, MA 02129
