Dear AFNI experts,

I am interested to know what could be the best approach to control physiological artifacts (respiration and pulse) without physiological records during the fMRI session. I am trying to use 3dDetrend or 3dTproject with higher order polynomials to control those low frequency signals. But, I read in a lot of papers that filtering (bandpass) can handle this situation very well. Do you recommend to apply 3dTproject with the bandpass option? As long as I know using higher order polynomials is similar to apply a filter. So, doing both things could be repetitive, Is that correct?


Thanks a lot,
Karel
