Hello,

I'm working on processing retinotopy data taken at 7T, and would like to do distortion compensation. To do that, I need to do all the preprocessing myself before invoking @RetinoProc, so I am also interested in a flag to skip the motion correction step. I see where to skip time slice correction and volume/surface registration to my functionals, but not where to turn off the 3dvolreg. Has than been implemented?

Thanks,

Andrea Grant
