I would need some help regarding the output of the simulation of stimulation (example below):
1. I am trying to find exactly what these outputs are and I believe that the “vat_left.nii” and “vat_right.nii” are binary mask of the VTAs. Would that be a correct statement?
2. As a follow-up to my question above, it seems that I am getting errors when I try to use these binary mask and doing simple command such as adding the masks. For example, in FSL, if I use the fslmaths -add with the “vat_right.nii” I get the following error message:
Error message following fslmath (e.g., fslmaths 1802_left.nii -add 1803_left.nii sum_left.nii.gz)
WARNING:: Inconsistent orientations for individual images in pipeline!
Will use voxel-based orientation which is probably incorrect – *PLEASE CHECK*!
Would you have any idea why? Is there something I should do on the VTAs output from lead dbs before trying to add them?
