I used the fat_proc_connec_vis command in the following way:

fat_proc_connec_vis -in_rois /Users/NET_000_ROI_GMI.nii.gz -prefix testing -trackid_no_or

and I got the following error messages:

*+ WARNING: output sub-brick 0 is all zeros!

What does this mean ?


*+ WARNING: Set TR of output dataset to 1.0 s
++ elapsed time = 0.1 s

Also this confused me.
