Dear Dr. Alfonso,

Would you have any recommendations on which form of detrending should be preferred for resting state and task fMRI data? Additionally, for task fMRI data, is the detrending performed on condition specific time series or on the whole time series in general? I understand that the detrending decision could be partially based on how long the time series actually is...my resting state time series is ~7 minutes and the task fMRI time series (overall) is ~8 minutes. Any insight in this matter would be much helpful.


Thank you
