Run selxavg3-sess with -svres. This will create a new folder called "eres" in the output analysis directory where the residuals will be stored. Assuming that you have mapped your data to fsaverage space, you can then create a post cing label (mri_annotation2label) and then use mri_segstats with --slabel fsaverage lh /path/to/postcing.label --id 1 --avgwf avgwf.dat
The avgwf file will have the time course you want

Dear Freesurfer experts
I have been going through the documentation trying to figure out how to extract the time series for an ROI (Posteriorcingulate) after removing the regressors that I put in my mkanalysis-sess. I have run the selxavg3.
- Is this time course what is in the meanfunc.nii.gz?
- If it is, how do I pull this out in matrix format (.mat) out of the where I basically get one mean adjusted value for the ROI at each timepoint? (e.g. For the Posteriorcingulate, I want 210 values representing the mean activation after removing the effect of my covariates wm and css for each of the 210 timepoints).
- Is this information in the X.mat file? If so, what is its location?
