[Camino-users] RESTORE question

[Ryan Muetzel]

Hello,

I'm interested in using the camino software to process some of our DTI data, specifically to compute the tensor using the restore method.

I've followed the tutorial on the website for using the restore method.  The algorithm completes and writes out the proper data.  I am using the 2nd method for estimating sigma (from estimatesnr, sigma_mult from the b=0 images).

However, I see this message:

"inverters.RestoreDT_Inversion invert"
"Maximum iterations reached without convergence. Final tensor:"

Is this message a problem?  I was initially worried the algorithm was falling back on the OLS/WLS method, but that doesn't appear to be the case (I see that warning message when I reduce the sigma substantially).  The FA maps look very reasonable, and quite similar to the output from FSLs dtifit/wls method.

Thanks in advance for any information! 

All the best,

Ryan
