Hi, Corinne,

I am sorry to disturb again. 

I realized why it still read "Make sure map_interpolation_method.flag = 0 for tensor fitting " after I have already set map_interpolation method. flag=0.

The reason is, even though I turn the interpolation off in DKEparameters.dat, it still show in the Terminal that map_interpolation_method.flag = 0. And that's the problem. But how am I supposed to do that when I cannot actually turn it off?

Diffusional kurtosis maps are in folder F:\A3
DKE processing parameters file is F:\A3\DKEParameters.dat
DKE log file is F:\A3\dke.log

So could you please tell me how can I deal with this? Und in the User's Guide, there is no details about how to deal with this...

And there is another problem, which is DKEparameters.dat will be created only when I run DKE first, then the document will be created. And that means I need to run it two times. Otherwise, how can I suppose to find the DKEparameters.dat document?

Best regards,
Xinman
