Plotting correlated misorientation axis on specimen reference frame

[YuvalBon]

Hi!

I'm trying to plot the misorientation axis of subgrain boundaries (meaning, boundaries with misorientation of 1 - 10 degrees inside a grain). I would like to show it in the sample reference frame.
I know I can calculate the uncorrelated misorientation axis in the sample reference frame (using 'calcMisorientation(ebsd)'), or calculate the correlated misorientation axis but in the crystal reference frame (here using 'grain.boundary.misorientation' or 'grain.innerBoundary').
It is possible to have the correlated MOA on the sample reference frame in MTEX?

Thanks much!
Yuval

Hi Yuval Would something like https://mtex-toolbox.github.io/HomepageOld/files/doc/GrainMisorientationAnalysis.html do what you want? cheers L Luiz F. G. Morales ScopeM & Structural Geology and Tectonics Group ETH Zürich

Thanks Luiz!

I followed this code and using 'v = axis(ebsd('Forsterite').orientations,oriRef)' I generated pole figures that looks like the example:

However, I am not sure I understand what these figures mean. (a) Are these the axis orientations of correlated or uncorrelated pairs of misorientations?, and (b) is that the sample reference frame (similar to a standard CPO pole figure where the X direction is east-west and Z direction is north-south)?
Best,
Yuval

Hi yuval Sorry, that was part of the old documebtation Have a look here https://mtex-toolbox.github.io/EBSDGROD.html In this case the ebsd.orientations of (in your case) olivine are conbined to the axis of the grain orientation reference deviation that you can calculate after you have grains calculated, essentially transforming the misorientationnaxes from crystal reference frame to sample reference frame. The sample reference frame is of course the same you setup when importing the data Does this make sense? Cheers Luiz Luiz F. G.

Yes! I believe this is exactly what I was looking for. Many thanks!
