Improve exportang function
The ang file exported using "exportang" function does not open due to crystal symmetry mismatch.
Could you please be a little bit more specific? What have you done? What was the error message ...
Thank you,
Ralf.
Dear Ralf,
Sorry for the very brief description initially.
I am using MTEX for parent grain reconstruction from martensite ebsd data. The code is running fine.
After reconstruction, I am trying to export 'parentEBSD' to .ang file.
The execution is successful but when I try to open this .ang file, I get an error in the TSL software.
I also tried to copy the header of .ang file which I use to calculate pre austenite grains to the exported .ang file. But this way TSL is just crashing and even not giving an error.
Also, the "parentEBSD" object have many "nan" values.
These are remaining even after using the following code.
Thank you for reporting this issue.
I just updated the function https://github.com/mtex-toolbox/mtex/blob/develop/EBSDAnalysis/%40EBSD/export_ang.m Could you please check whether this resolves your problem?
Ralf.
Dear Ralf,
The problem still persists. I am attaching a snapshot of the .ang file generated from the updated code.
The crystal symmetry identifier is missing on line no. 11. Also,
I was wondering whether putting 0 for "#NumberFamilies" is a valid format or not. So I tried putting 0 for "NumberFamilies" in the .ang file generated by TSL and it was working fine.

The problem with the symmetry identifier is now resolved. But TSL is still showing the same error message.
You can see the content of .ang file in the image below. I think MTEX converts nan values of Euler angles to zeros.
Could you please by hand replace the 129 by 43 in the ang file?
Thank you very much for your help.
Ralf.
