I'd like to regress out the motion parameters from a dataset for analysis and also save the regressed timeseries for analysis elsewhere. I've been using a 2 step 3dDeconvolve method to do this a) regress the motion parameters and save the errts file (regressed timeseries), b) analyse the regressed timeseries as usual (as opposed to using stim_base for each motion regressor in one 3dDeconvolve command where I can't seem access to regressed timeseries?). I think this is a correct way of doing this but the errts file is centered about 0 but not scaled, which is giving me trouble in getting proper % change values from the beta weights. Is there a more clever way of doing this?

Thanks,
Jen
