Thank you for your reply! I have tried the directional fitting instead of tensor fitting and I found these pixels disappear and the fitting results became coherent. So what's the difference between these two fitting methods? If I acquired data in >15 directions, which methods could be more accurate? By the way, is there any requirements on adjusting the B-0 threshold?

Hi!
Check out the masking feature. By default, DKE uses a threshold value of 50 in the B-0 value to create a brain mask. Just by glancing at your image it looks like this is animal data and so your threshold might have to be adjusted?
Just so you know, we are phasing out support for DKE and have moved to a more modern software that will be monitored more closely. The documentation can be found here: https://pydesigner.readthedocs.io/en/latest/
I apologize for the delay!
