Import HKL channel 5 ebsd data by wizard

[Shuang Xie]

Hi there,

Maybe it is a very simple question...

By using the Import Wizard to input HKL channel 5 ebsd data, which of the selection should I choose in the " Specimen Coordinate system", what are they meaning, especially for the highlight two? 

Cheers,

Shuang Xie

I import .ctf data that's been exported by Bruker software, and I use the 'use CTF interface flag'ConvertEuler2spatialreferenceFrame', which will only have an effect if your system uses two separate coordinate axes, one for the spatial, and one for the Euler.  This has been the case in the past with the Bruker Esprit 1.9 software.  If the system has only one set of axes (as for Bruker Esprit 2.0) it will have no effect.

My advice is to open your data with the analysis software attached to the EBSD instrument, and note the orientation of the EBSD map, the Euler angles of some selected grains (eg the ones in the corners) and finally a pole figure showing those angles.  They should also indicate the x-y orientation they use by labeling of the pole figure.  If all three of these are correct, the importing is correct.  If you have two separate coordinate systems it is possible to have the correct map layout, the correct Euler angles, and the incorrect resulting pole figure, so check all three.
