5ttgen warning

Hi, I’m trying to run 5ttgen and i get the following warning:
5ttgen: [WARNING] Generated image does not perfectly conform to 5TT format:
5ttgen: [WARNING] 5ttcheck: [WARNING] Image “result.mif” contains 3 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)

I don’t know why and hope someone could help me :sob:

Dear @JQ.Zhang ,

Perhaps have a look at this thread

Cheers,
Nick
