Hello, Freesurfer experts:

I followed the tutorial for FStutorial/diffusion:

https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Diffusion

FsTutorial/Diffusion - Free Surfer Wikihttps://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Diffusion surfer.nmr.mgh.harvard.edu The purpose of this tutorial is to give you experience with the integration of Diffusion Tensor Imaging (DTI) with FreeSurfer. The data were collected at MGH as part ...

And i export the variables and run the command dt_recon both on my MAC and Ubuntu for the tutorial subject which located in:

TUTORIAL_DIR=$TUTORIAL_DATA/diffusion_tutorial/Diff001

Just to be sure, So I run it on both systems, and I got the same errors:

I think the problem is from fitting tensor, so do you think it is the problems of you tutorial data, I know you are going to release the new version, but anyway, this should be work, no?
