Issue on exporting data: unindexed pixels(points) being converted to indexed pixels. #1037

Open AmitS07 opened 4 weeks ago

AmitS07 commented 4 weeks ago

Hi DREAM3D community,

I face the following issue while exporting data from "ctf" to "ang". My raw EBSD data is in .ctf file. I just want to correct its reference basis actors. To do so, I am using following Pipeline (shared below) Pipeline_reference_correction.json

It does change the basis vectors. But, unfortunately, the unindexed-points change to indexed points i.e. phase of unindexed pixels changed from "0" to "1". All unindexed pixels' orientations became "red" instead of "black". This might be due to the fact that I am not able to use the "Mask_error" (a Mask based on "Error" metric of ctf data with threshold of Error=0).

Please let me know how and which filter should be used to ensure unindexed-pixel's phase remains the "0" and should not convert to "1".

For reference, I am attaching the two IPFZ plots (1) plotted with directly DREAM3D, (2) from TSL-OIM from the exported data (1) DREAM3D IPF image- R3_mid_redo_6_IPFZ_dream3d

(2) Plotted in TSL-OIM from the exported data (in .ang) R3_mid_redo_6_IPFZ

Please check my pipeline and let me know what to add, meanwhile I am trying to fix this.

I think in DREAM.3D version 6.x there may be an issue where sometimes the phase values will be changed from zero to 1.

Currently I'm not seeing the issue with your data? the black pixels from the dream3d generated images seem to correlate to the pure red pixels from the TSL images?

@AmitS07 Could you post the .ctf file?
