Hello,

I am using MATLAB R2014b, NODDI_toolbox_v1.01, and niftimatlib-1.2.
I make brain_mask.nii by FSL BET.
I am getting the following error.

142030 of voxels to fit
Fitting voxel 1
Error using svd
Input to SVD must not contain NaN or Inf.

Error in pinv (line 18)
[U,S,V] = svd(A,'econ');

Error in FitLinearDT (line 35)
Xi = pinv(X);


Error in GridSearchRician (line 57)
D = FitLinearDT(Epn, protocol);


Error in ThreeStageFittingVoxel (line 66)
[x0 liks] = GridSearchRician(Epn, modelname, grid, protocol, constantsGD, sig);

Error in batch_fitting_single (line 71)
[gsps(i,:), fobj_gs(i), mlps(i,:), fobj_ml(i), error_code(i)] = ThreeStageFittingVoxel(voxel,
protocol, model);

Anyone know whats the issue and how to resolve it?

Thanks,
Tabei

Hi Tabei,

Can you copy and paste the text within your b-value file?

Have you had a chance to go through the tutorial on how to explore DWI data?  If you have, can you produce a few signal plots like the ones shown in that tutorial?
