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

Best,

Steven

Subject: Re: [Freesurfer] Physiological Noise Regression from rsMRI

 

You will just need to create a text file with one or more columns, one for each regressor put this in the run folder (same folder where the raw data are). When you run mkanalysis-sess, add
-nuisreg filename N
where N is the number of columns you want to include

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
