After several hours, this script crashed with the error: qsed: .commands: no such file or directory sed: .commands: no such file or directory The full output is below. I also noticed that the file xxx_FAi_to_target_nonlinear.nii.gz has a range different than the input: (-65.45, +43.75) vs. (0, +12000). Any guidance will be welcome...
