Dear all,

I'm having almost the same problem. I loaded the gradient table (60x3, since I have a DKI dataset with 30 directions with a b-value of 1000 and 30 directions with a b-value of 2000) and DKE actually shows the gradient table after I load it, so I guess it can read it correctly. I then load the 4D NIfTI file, which consists of a b0 image at the beginning, followed by 60 directions (30 b=1000 and 30 b=2000). I start the processing procedure, but it crashes with the error: "Index exceeds matrix dimensions. Error in dke_estimate (line 188). Error in dke (line 182). MATLAB:badsubscript". Is there anything I'm doing wrong here?

Any help would be appreciated.

Thanks,
Ehsan
