regressing out is the analysis. You'll have to create an "analysis" with mkanalysis-sess, then run selxavg3-sess with -svres to save the residual.

Dear Freesurfer expert:
  After I used ' fcseed-config' to get wm.dat and csf.dat, how could I get the signal of each voxel that regresses out the nuisance. I do not want to do the analysis. I just want to get the signal after regressing out nuisance.
  Thank you
