I plan to use FSL for preprocessing my event-related FMRI data (brain extraction, motion
correction, registration), but to perform deconvolution analyses using AFNI 3dDeconvolve. I have
looked through the MCFLIRT page, the archives, and the faq and couldn't find the answer to this
question. What are the six columns in the MCFLIRT transformation parameters file generated by
the -plots option? I want to use these motion parameters as variables of no interest in the
regression analysis, but want to know exactly what each is. Thanks in advance for all help.
