Import EBSD data
Importing EBSD data can be done guided by the import wizard
import_wizard('EBSD')

or directly by the command loadEBSD
% specify file name fname = fullfile(mtexDataPath,'EBSD','Forsterite.ctf'); ebsd = loadEBSD(fname,'convertEuler2SpatialReferenceFrame')
ebsd = EBSD Phase Orientations Mineral Color Symmetry Crystal reference frame 0 58485 (24%) notIndexed 1 152345 (62%) Forsterite light blue mmm 2 26058 (11%) Enstatite light green mmm 3 9064 (3.7%) Diopside light red 12/m1 X||a*, Y||b*, Z||c Properties: bands, bc, bs, error, mad, x, y Scan unit : um
Correct EBSD data
The EBSD data are now represented by the variable ebsd. Which is essentially a long list of x and y values together with phase infotmation and orientations. To acces any of these properties do, e.g., the orientations of the Forsterite phase do
ebsd('Forsterite').orientations
ans = orientation size: 152345 x 1 crystal symmetry : Forsterite (mmm) specimen symmetry: 1
% EBSD data is stored in the class <EBSD_index.html EBSD> while grains are % stored as variables of type <grain2d_index.html grain2d>. The following % mindmap may induce a general idea analysing EBSD Data with MTEX. % % <<grain.png>> % %
Modelling Grains
Grains are a basic concept for spatially indexed EBSD Data. With grain modelling comes up the possebility getting more information out of EBSD Data - e.g. fabric analysis, characterisation of misorientation
Analyzing EBSD Data
Visualizing EBSD Data is a central to understand a specimen. The most naive way is plotting of the individual orientations as pole point plots or spatially indexed in some map with colorcoded orientations. Moreover one gets with grains the possibility to take a closer look on grain boundaries.
Estimating ODFs from EBSD Data is of interest, furthermore selecting the optimal halfwidth is a difficult question, in particular in matters of grains.
