Dear FSL experts,
I'm running dtifit command as follow:
dtifit -k DWIforfit -m nodif_brain_mask -r DWIbvecs -b DWIbvals -o DTI --sse --save_tensor
and everything went smoothly! However when I'm going to fit the tensor with weighted least squares by adding the --wls command as follow:
dtifit -k DWIforfit -m nodif_brain_mask -r DWIbvecs -b DWIbvals -o DTI --sse --save_tensor -wls
I got this weird error:
0 256 0 256 0 71

Any tips?
Thanks
