Hi,

I'm trying to use DKE with dki data taken on a Philips system.

I've the 4D nifti file and a bvec file and a bval file. Each row of bvec is the gradient direction (unit norm'd vector) and there is a corresponding row in the bval. I acquired a single b=0 image, 32 b=1000, and 32 b=2000 images.

I'm running the 64 bit version 251 on windows 8.1.

I can choose my bvec.dat file, but then b-values field in the DKE parameter window defaults to [0 1000 2000] should I change that to be [0 1000 ... 1000 2000 ... 2000] (there there are 32 total repeats of 1000 and 32 total repeats of 2000)?

When I tried that the software crashed.

When I leave the b-values to be [0 1000 2000] I get the error: "Processing failed with message: No error" in the GUI and "bad subscript" error in the command window.

I'm attaching screen shots.

My NII file is:

fslinfo 20140617_102324IM_0001WIPDKI32DIRSENSEs1001a1010
data_type INT16
dim1 96

cal_max 0.0000
cal_min 0.0000
file_type NIFTI-1+

And I'm attaching the bvec.dat file.
