Unlike most other texture analysis software MTEX does not have any graphical user interface. Instead the user is suposed to write scripts. Those scripts usually have the following structure

  1. import data
  2. inspect the data
  3. correct the data
  4. analyze the data
  5. plot and export the results of the analysis

During all these steps the data are stored as variables of different type. There are many different types of variables (called classes) for different objects, like vectors, rotations, EBSD data, grains or ODFs. The sidebar on the left lets you browse through all different MTEX class and the corresponding functions.

Variables are generated automatically when data are imported. E.g., the command

ebsd = EBSD.load('fileName.ctf')

imports data from the file fileName.ctf and stores them in the variable ebsd of type EBSD. In the command window the variable ebsd is displayed as follows

ebsd = EBSD (show methods, plot)

 Phase  Orientations     Mineral         Color  Symmetry  Crystal reference frame
     0   58485 (24%)  notIndexed
     1  152345 (62%)  Forsterite  LightSkyBlue       mmm
     2   26058 (11%)   Enstatite  DarkSeaGreen       mmm
     3   9064 (3.7%)    Diopside     Goldenrod     12/m1       X||a*, Y||b*, Z||c

 Properties: bands, bc, bs, error, mad, x, y
 Scan unit : um

Next one can pass the variable ebsd to diferent MTEX function. E.g. to plot the EBSD one simply does


The grain structure is reconstructed by the command

grains = calcGrains(ebsd)

which returns a new variable, here called grains

grains = grain2d (show methods, plot)

 Phase  Grains  Pixels     Mineral  Symmetry  Crystal reference frame
     1    1256  152345  Forsterite       mmm
     2     518   26058   Enstatite       mmm
     3    1526    9064    Diopside     12/m1       X||a*, Y||b*, Z||c

 boundary segments: 45832
 triple points: 3863

 Properties: GOS, meanRotation

which is of type grain2d and contains the entire grain structure. Finally, we my visualize this structure by
