you could try to run mkanalysis-sess with -notask and your nuisance regressors specified as -nuisreg, then run selxavg3-sess with -no-con-ok and -svres to save the residuals. maybe that solves your problem? caspar

I like to regress out the linear drift, mean, and head motion generated by the motion correction step of fsfast from the raw time course only. Is it possible using fsfast?

Sorry, I don't follow what you are asking. FSFAST does not do any drift removal from the raw data, all of that is in the design matrix doug

Hi,
The analysis necessary to my study is to run some analysis on the raw time course data. Before working on the raw time course data, it is necessary to remove linear drifting, mean, and head motion. Can I just specify those parameters without having conditions in the steps of generating design matrix? If so, what command should be used?
Thanks, Xiaomin Yue
