Eduardo,

The SLOMOCO companion script is actually also intended to be used with PESTICA to correct for head motion in parallel with physiologic noise. Basically, you run PESTICA, then you run SLOMOCO with the -r flag (and be sure to specify the same file you specified as input EPI data for PESTICA, NOT the corrected post-PESTICA file) and it will run a slicewise motion correction and at the end, it will regress out a slicewise motion model, PLUS the PESTICA physiologic noise signals in parallel. It doesn't support WM, CSF or global signal - there is some controversy whether WM, CSF or global signal are safe corrections so i have not supported additional regressors at this point.
