Problem loading 3D EBSD data

[aplowman]

What do you want to do? Load 3D EBSD data from a series of .ctf files, representing slices through the material. I would actually like to use the grain segmentation algorithm within MTEX on data from full-field crystal plasticity simulations. But I thought I would start by trying to load some experimental data.

What data do you have? A series of .ctf files

What code do you use? The following script was generated by the import_wizard for loading a series of EBSD images.

%% Import Script for EBSD Data
%
% This script was automatically created by the import wizard. You should
% run the whoole script or parts of it in order to import your data. There
% is no problem in making any changes to this script.

%% Specify Crystal and Specimen Symmetries

% crystal symmetry
CS = {... 
  'notIndexed',...
  crystalSymmetry('6/mmm', [3.2 3.2 5.1], 'X||a*', 'Y||b', 'Z||c*', 'mineral', 'Zirc-alloy4', 'color', [0.53 0.81 0.98]),...
  crystalSymmetry('m-3m', [3.5 3.5 3.5], 'mineral', 'Zr', 'color', [0.56 0.74 0.56])};

% plotting convention
setMTEXpref('xAxisDirection','north');
setMTEXpref('zAxisDirection','outOfPlane');

%% Specify File Names

% path to files
pname = 'path\to\data';

% which files to be imported
fname = {...
  [pname '\Slice 1\ebsd maps 001.ctf'],...
  [pname '\Slice 2\ebsd maps 002.ctf'],...
  [pname '\Slice 3\ebsd maps 003.ctf'],...
  };

%% Z-Values

Z = [
  1,...
  2,...
  3 ];

%% Import the Data

% create an EBSD variable containing the data
ebsd = EBSD.load(fname,CS,'interface','ctf','3d',Z,...
  'convertEuler2SpatialReferenceFrame');

What result do you get

I get an error:

Unrecognized property 'z' for class 'EBSD'.

Error in EBSD.load (line 96)
    ebsd{k}.z = repmat(Z(k),length(ebsd{k}),1);
    %#ok<AGROW>

Error in CD_Zr_example (line 41)
ebsd = EBSD.load(fname,CS,'interface','ctf','3d',Z,...

What result do you expect A successfully loaded ebsd object.

What MTEX version do you use? 5.7.0 on Matlab R2020a

Thanks!

Hi, 3D EBSD support in mtex has been dropped many years ago. Cheers, Rüdiger

Thanks for the info.
