[Dipy] Re: [DIPY] FWDTI and DTI recon questions including if default output is upper or lower triangle

Hi Dipy developers and contributors, First, thanks for this amazing tool. I have exactly the same problem. When trying to model the dti tensor with free-water correction: "RuntimeWarning: overflow encountered in exp". It looks like the tensor is finally calculated and the images look good (aparentely), but I wonder if there might be any errors in the process. Anyone has an answer for this?
