Just a quick follow-up question, For FD/DVARS or other "censoring" criteria -- using -tpexclusion worked great for surface based analysis with mkanalsysis and selxavg3. Is there a way to do this for seed-to-seed analysis (fcseedcor)?
Thanks!

Yes,you need a time point exclusion file (-tpexclude filename option to mkanalysis-sess). Run mkanalysis with -help to get more info on how to create it.

Hi Freesurer experts,
I’m looking to censor (drop volumes) from my resting state fMRI time series that violate a predetermined motion and signal threshold (FD and DVARS). I've already determined which volumes violate X and Y criteria.
Is there a way to to tell FS to "ignore" these time points in the analysis such as in preproc-sess or mkanalysis-sess?
If there is not and if I were to drop the volumes directly from the 4D file before starting any pre-processing and analysis – would that be a problem for finding and regressing the auto-correlation in the time series?
Thanks! Adam
