Hi there,
I am currently using the FATCAT commands in order to combine fmri and dti data.
However, I noticed that after performing the dual regression (on the functional data), in order to get z-score maps at the subject level, each subject contains a different number of ROIs (3dROIMaker step). We don't get the same number of ROI's across all subjects. Do you have any suggestions on how I can overcome this?
I was wondering if there was some way around this issue. I know with 3dNetCorr there is a "push_thru_zeros" option but how about the DTI side? Is there a way to run 3dtrackID without getting errors based on the different number of ROI's?
Also, how should I deal with a different number of ROI's per subject, when it comes to statistical analysis?
Thanks for your time.
