Hi,
I was using a customized pipeline to compute intragranular misorientation (IGM) and kernel average misorientation in addition to grain bounda character distribution (GBCD) for 3D grain map obtained by synchrotron diffraction contrast tomography (DCT).

The pipeline works, however, the computed IGM and KAM seem to be quite smaller thant I computed with my own code. Is there anything I did wrongly or maybe something else ? Really hope someone can help me have a look.

Attached I am sharing the json pipeline.
I will also be willing to share the data so you can dig into it.
I was using Dream3D 6.5.171 to process and visualize with Paraview 5.11.1.
Thanks a lot in advance !

Dear  Haixing,
      I think we would need to see the results that you expected to get versus what you actually got before we could render any opinions on the data.

You may want to upgrade to DREAM3D-NX (https://www.dream3d.io. Free for students) if you are able that that version is much better tested.
