[Neuroimaging] Question about DIPY MAP-MRI model

Dear DIPY developer,
I am a  user of DIPY and find MAP-MRI model is very useful. During my testing, I found a potential error here for non-gaussian (NG) parameter. The NG and NG perpendicular maps looks not correct as a low intensity was observed at WM area, and the NG parallel maps looks like a NG contrast.

Here the data  I test is using a 2 shell DWI data (b 0, 1000, 2000, 64 dir each shell), a DSI data was also test with similar result with Q4 half setting.

I like the DIPY tools and MAP-MRI model here, can you help with the problem?
