Hi Mona, I don't understand your question. Only the mean will be removd from the time series, no drift term. One usually does not consider the hemodyamic response delay to be a drift term

Hi
I wanted to follow up on this question and clarify it a little bit more. My question is if the temporal drift (hemodynamic response delay) has been counted in considering that I used the preprocessed data as the input? I deeply appreciate any help.
Thanks Mona

Hi Freesurferes
I have extracted timeseries from a task fMRI using the command below: mri_segstats --i fmcpr.sm0.self.rh.nii.gz --slabel $subj rh rh.label --id 1 --avgwf-remove-mean --avgwf ./rh.txt
My question is: Is the temporal drift being counted in considering that I used preprocessed data as the input?
Thanks Mona
