If I convert my time series to % signal change (a(t)/mean(a)*100) will the values of the regression coefficents returned by 3dDeconvolve reflect % signal change values?
If I did not scale the data prior to 3dDeconvolve how could I obtain % signal change values from the regression coefficents?
I have several non-linear drifts due to a long run and irregularities in scanner function. Should I attempt to correct these drifts using a high pass filter implemented using 3dFourier or can I detrend the time series within 3dDeconvolve itself?
Thanks.
