Hi,
I am trying process Resting State (RS) data. One of the steps includes regressing out the physiological noise. RETROCICOR works fine for the subjects for whom I recorded the cardiac and repiratory phase data using external monitoring system during the RS scan. However, for some of the subjects, I don't have that phase data. Is there any way to generate those physiology regressors without cardiac and respiratory phase data?
Thanks,
Kausar Abbas
