Hi Doug, Thanks for the information about how FS whitens the data. Is there a way to temporally whiten data without running a GLM (i.e., without running selxavg3-sess)? Alex On Tue, Jan 22, 2013 at 9:58 AM, Douglas N Greve wrote: > > On 01/19/2013 03:18 PM, Alex Kell wrote: > > Hi Freesurfe

Hi Freesurfers, I have two unrelated questions. 1. I want to pre-whiten some functional data without running a GLM on them (we're going to run the GLM in matlab). It looks like fsfast does autocorrelation correction as a part of the selxavg3-sess wrapper. I tried poking around on the wiki and m
