Hi Clementine,

Without having a copy of your current parameter file, bvecs, and example dataset, etc., providing advice to you will be difficult.

Remember that you don't need a bvecs line for b0, and that you would be using the save bvecs for each b-weighting, so bvecs should have the number of lines equal to your number of directions.  

According to your original parameter file, I presume you have used 30 directions.

I note that you only specify bval = [0 1000] which means you can't reconstruct the kurtosis tensor, only the diffusion tensor.  Did you do two non-zero b-values?

The following won't affect whether DKE runs, but I would:

(a) change fwhm_img to match your acquisition resolution (currently you have 2.7 mm isotropic).

(b) change map_interpolation_method.resolution=1 (which is in mm, so should also be adjusted, or turned off with the flag two lines above.

If you attach an example dataset, etc. I will see if I can get DKE to finish on my machine.

Cheers,

Kirk
