Create a subset for a defined orientation +/- tolerance

[aleslagter]

Hello! This might be a very simple question, but I am new to matlab and mtex.
I am loading an EBSD map and plotting pole figures, but I would like to be able to create subsets of the data for a certain orientation and with a defined tolerance.
I have all the orientations for a phase loaded on

o= ebsd('Zr02').orientations;

and can plot for certain planes h using
plotPDF(o,h)

but I would like to segment the orientations and create subsets, and also to be able to plot the maps of those orientations.

Thank you for any suggestions!

Probably someone has an even better approach than this... but if you can define one-or-more reference orientation/s of interest, you can compute the angular deviation of any other orientations... and then you can plot the EBSD points colored by the angular difference to visualize their spatial distribution in a map.

Thank you! I found now the following online and I think it works well

o2 = orientation.byEuler(5degree, 80degree, 120degree,ebsd('Zr02').CS);
grains_selected = grains.findByOrientation(o2,20degree)

Thank you!
