I see that 3dDeconvolve is an OLSQ regression and 3dREMLfit is a GLSQ. I was under the assumption that 3dDeconvolve handled autocorrelation of the time series since this seems to be important in fMRI data. Is this true, or is 3dREMLfit the only program that does so? If this 3dREMLfit is the only program, then in what instances would one use 3dDeconvolve? Shouldn't all fMRI data be handled with taking autocorrelation into account?

Best,

Andrew
