When I write the FNIRT command (fnirt --in=structural_image.nii.gz --aff=structural_brain_FLIRT_2mm.mat (obtained after FLIRT command) --config=T1_2_MNI152_2mm.cnf --cout=output_name_fc --iout=output_name --jout=output_name_jf --jacrange=0.1,10) a warning message appears in the terminal: Warning, Jacobian not within prescribed range. Prescription is 0.1 -- 10 and obtained range is 0.0929198 -- 3.87726. Although this message, the output image seems to be ok so, must I do anything to correct it? what can be the consequences of doing this process like this?
