Fail to instantiate module "GradQC" with Slicer 4.11

[maohy915]

After I install DiffusionQC extension, there comes an error whenever I start Slicer:

Traceback (most recent call last):

Hi, sorry about the error. I believe it is due to issue #42. Recently Slicer 4.11 has changed in a way that requires us to import functions in a different way which I haven't gotten the time to do yet.

In the meantime, can you get a Slicer-4.10, affect this fix, and thereby use GradQC?

I reinstalled Slicer-4.10 version, but didn't find DiffusionQC Extension at all...

That is weird.

Type DiffusionQC in the search bar, it should show up and let you click INSTALL.

Thank u.
I made it work in Ubuntu. (But still didn't work in windows. )
I tested it with sample dwi image in method i), and failed with another error:

Traceback (most recent call last):

Are you saying you did https://github.com/pnlbwh/SlicerDiffusionQC#tests (i) ?

In any case, can you try (ii) ?
