Hi experts,

I am using proc.py to preprocess resting state images, closely following the pipeline laid out in example 11. The options for motion regression include demeaning the 6 motion parameters and entering their derivatives (i.e., 12 total terms). I was wondering if there is a way to expand the motion parameters to 24, for example, in line with Friston's 24 parameter model.

Friston, K.J., Williams, S., Howard, R., Frackowiak, R.S., Turner, R., 1996. Movement-related effects in fMRI time-series. Magn Reson Med 35, 346-355.

Thanks in advance,
Jenna Blujus
