load Orientation data from generic text files
Description
loadOrientation_generic loads individual orientations from text or exel files that have a column oriented format as
phi1_1 Phi_1 phi2_1 prop1_1 prop2_1 phi1_2 Phi_2 phi2_2 prop1_2 prop2_2 phi1_3 Phi_3 phi2_3 prop1_3 prop2_3 . . . . . . . . . . . . . . .s phi1_M Phi_M phi2_M prop1_M prop2_M
The assoziation of the columns as Euler angles, phase informationl, etc. is specified by the options ColumnNames and Columns. The files can be contain any number of header lines.
Syntax
[ori,prop] = loadOrientation_generic(fname,'ColumnNames',{'Euler1','Euler2','Euler3','prop1','prop2'})Input
| fname | file name (text files only) |
Output
| ori | orientation |
| prop | struct with fields for the additional columns |
Options
| ColumnNames | names of the columns to be imported, mandatory are euler 1, euler 2, euler 3 |
| Columns | positions of the columns to be imported |
| RADIANS | treat input in radiant |
| DELIMITER | delimiter between numbers |
| HEADER | number of header lines |
| BUNGE | [phi1 Phi phi2] Euler angle in Bunge convention (default) |
| ABG | [alpha beta gamma] Euler angle in Matthies convention |
| PASSIVE |
Example
fname = fullfile(mtexDataPath,'EBSD','85_829grad_07_09_06.txt');
CS = crystalSymmetry('m-3m','mineral','Mg');
SS = specimenSymmetry('triclinic');ori = loadOrientation_generic(fname,'CS',CS,'SS',SS, 'ColumnNames', ...
{'Euler1' 'Euler2' 'Euler3'},'Columns',[5,6,7],'Bunge')ori = orientation (Mg → xyz (-1))
