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
