Can anybody suggest to me why the IPF map looks like this? (Pic attached). This one after cleaning the data and exporting it in JPG/TIF format. No boundary for grains..
Thanks and regards

I recommend using the Mtex toolbox (https://mtex-toolbox.github.io) for processing and plotting of EBSD data

Hi Subha,
Hopefully your question was already answered, but if not, do you expect any deformation in your material? If so, then the IPF map of individual grains will show some spread. Higher resolution scans can help resolve the local changes of orientation (if that is what you are interested in).
If you are expecting a fully recrystallized/annealed sample, then the IPF coloring of individual grains should be more uniform. In which case, the current map suggests that there is still some surface deformation from the sample preparation. Hope this helps!
Thank you Brian Lin for your answer. This map was of as-cast one. I think you are right. Although I did vibrometry polish for 21 hrs in colloidal silica suspension (0.05um) after alumina cloth polishing (0.3um), still some surface deformations remained.
Thanks and regards

Hi Subha,
I agree with Tijmen Vermeij the MTEX toolbox gives you this ability and many other tools for microstructure and texture analysis. You may also have a look on the add-on function library of ORtools:

Hope they work for you as well.
Kind regards,
Hamid
