There are warnings when 5ttgen.
Here are my commands:
5ttgen fsl T1w_bet.nii.gz 5tt_nocoreg.mif -premasked
and the warnings:
5ttgen: [WARNING] Generated image does not perfectly conform to 5TT format: 5ttgen: [WARNING] 5ttcheck: [WARNING] Image "result.mif" contains 8 brain voxels with non-unity sum of partial volume fractions 5ttgen: [WARNING] 5ttcheck: [WARNING] Input image does not perfectly conform to 5TT format, but may still be applicable (suggest re-running using the -masks option to see voxels where tissue fractions do not sum to 1.0)
what may cause this? How can I ensure these errors whether influence the following tractography?
