Detailed description of head motion scrubbing regressors

Submitted by YML on

Dear Yan,

I did a "head motion scrubbing regressors" in the nuisance regression step in DPARSFA in my study. The reviewer asked me how this was performed in detail. I know this is different from the "scrubbing" at the bottom of DPARSFA, so it's inappropriate to cite Power et al., 2012. But is there any reference that I can refer to? Is the processing the same to what the FSL's motion outliers tool (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FSLMotionOutliers) does?

Thank you so much.

Hi Minlan,

It's similar to Saterthwaite et al., 2013 Neuroimage, and Yan et al., 2013 Neuroimage: scrubbing regression or spike regression.

Each bad time point is a single regressor.
