Import Nanomegas Astar data

[Eric Leroy]

Hello,

I work on a TEM with the Nanomegas software called Astar that is a soft for automated crystallographic identification. The results are similar to the one obtained by EBSD. In order to treat data more completely, I want to import them into MTex. Astar is able to export data in .ang format. I make the exportation by Astar and the importation in Mtex fails. The software tells me that it can not recognize the data format and opens the generic file import dialogue. Can you tell me if you see any problem in the datafile and how to import data into Mtex ?

Thank you

Best regards

Hello,

you can use loadEBSD_generic function. In this case, each column should be specified explicitly after keyword 'ColumnNames'.

I am not familiar with Astar files but I think that the first three columns contain Euler angles followed by X and Y coordinates (4th and 5th columns).

Then, data from the file can be imported with the following script:

angFile = 'T40-DL-fluage-1.ang';

CS = symmetry('6/mmm', [2.95 2.95 4.686], 'X||a*', 'Y||b', 'Z||c', 'mineral', 'Titanium', 'color', 'light blue');
SS = symmetry('triclinic');

ebsd = loadEBSD_generic(angFile,'CS',CS,'SS',SS,'ColumnNames',{'Euler 1' 'Euler 2' 'Euler 3' 'X' 'Y' 'IQ' 'CI' 'Phase' 'Fit'},'Bunge','radians');

figure; plot(ebsd)

This script assumes that Euler angles are in radians and in Bunge definition (is it right?). If you know what information is stored in the other columns, you can replace column names 'IQ' 'CI' 'Phase' 'Fit' with the actual ones for further processing.

Figure obtained with the script is attached.

Hi, if you have the new version of mapviewer from ASTAR you can export as channel 5 project (.cpr) and then it is easily loaded into MTEX.

Hope this helps,

Al

Hi,
Yes, we have it. I will try this, thank you for the tip. I had an other answer early that works also. Thank you everybody far the help.

Best regards

Eric
