Hi all,

I am currently developing a pipeline to remove physiological noise (respiratory and cardiac) from rsMRI images. I am at the point where I have created the regressors using fast_retroicor.m from the physiological data logs. When I add the columns of the regressors up and plot the result, it appears to create pulses at the times when the physiological data peaked. I was wondering if anyone knows how to incorporate the regressor files into FreeSurfer. Please let me know at your earliest convenience.

Thank you,

Steven
