I am working with the lateast version of MITK DIFFUSION (in windows 7 and 10 OS).The problem is about diffusion kurtosis maps especially K map and color display of this map.

Dear babis,

thank your for reporting an issue. Could you please enter a meaningful title and describe what the actual problem is?

Could you please describe what the actual problem is?

when i am trying to generate K map the output is a color(red) image and sometimes software crushes.

Can you provide test data so we can reproduce the issue?

{F1158489}yes i will send you now{F1158486}

Could you zip these files? Otherwise I have to download them one by one.

It looks like there are only b=0 volumes in this dataset. Did you send me the complete dataset? What b-values should be there?

I can't reproduce the carsh but the visualization is off sometimes because of the level-window setting. Could you try adjusting your level windo to something like (3,6)? The fit seems to produce many negative values which messes up the visualization.
You could also enable the checkbox "Boundaries for K", which avoids negative values for K in the first place.

Let me know if this helps.

Is this resolved?

I apologize for late response.
yes it is resolved.
I want to ask about the preprocessing module of diffusion.the 'project onto shell" seems to be as 'calculated b values". I have tried on breast and liver diffusion with target b value higher than aquired and looks like calculated b value.
is that true?

Yes, that is correct.
