RE: Error when running DKE: svd
Hi Michael,
Do you have any 0 vectors in your gradient vector files? The vectors in your gradient vector files should correspond to nonzero b-values.
The gradient vectors are normalized by the program after being read from file. If any of the lines in a gradient vector file are all 0 values, the calculations will produce NaN values in the matrix that is input to SVD.
Hope this helps,
Dave
