Also, I currently have one regressor file for cardiac noise and one for respiratory, each with multiple columns (each column representing a Fourier decomposition term). Should I consolidate these two txt files into one txt file, or should I call -nuisreg twice? Thanks again.

At what point in the processing pipeline should this happen? For example, should this happen before or after skull-stripping?

When you run mkanalysis-sess, add -nuisreg filename N where N is the number of columns you want to include On 10/18/18 10:34 AM, Meisler, Steven Lee wrote: 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 -------------- Steven L. Meisler, M.S.E.
