Should I remove any components that appear to be movement and noise before proceeding to the dual regression?Thanks,CaseyOn Mon, Oct 19, 2015 at 2:48 PM, Stephen Smith <[log in to unmask]> wrote:Hi - are you running with more group-level components than individual-dataset-timepoints?Cheers, Steve.On 19 Oct 2015, at 00:24, Casey Paquola <[log in to unmask]> wrote:Hi FSL experts
I'm running melodic and dual regression on a group 55 subjects. When I reached the dual regression stage I received an error message of "DOF cannot be zero or negative!" in drC. I tried to check the stats/dof for each subject (as has been suggested in other posts) but found the stats folders from melodic were empty for each subject despite ticking Output Stats folder in the melodic setup. Is the missing output from melodic the reason for my error message in the dual regression? And if so, do you have any suggestions as to how to fix it?
I've attached my melodic set up design.
Thankyou for any help,
Casey
