Hi Stefano,

yes, it fits the DTI model using linear least squares.

Cheers,

So DTIfit still works with linear fitting, is that right?

This was for BEDPOSTx and I don’t see it in the changlog (under whats new).  It happened in 4.1.5.
 
Peace,

Matt.

With which version of FSL was the tensor fitting changed from linear to non-linear (I think I read on the list that this was the case, but I could not find this detail on the website)? Can someone point me to where this type of details would be contained on the website?
