Generating pole figure for random orientations in hcp

[vamsi1712]

I am trying to generate pole figure for random orientations in a Bismuth Telluride alloy ( HCP structure). I have my random orientation in an excel sheet. So my question was will I be able to use them in your python code (like you called files in your AZ31 alloy texture example).

Also I have some ebsd files which are in .oim format. Can I use this extension in your python code to generate pole figures? If so how can I do that.

1. You should export the the random orientation in the excel sheet to a file that is readable by "upf.polefigure" class.
   The "upf.polefigure" allows two types of input data.

a). texture files compatible with VPSC. Particularly, it can read a file with 4 dummy head lines that is followed by discrete orientations written in the Bunge convention.
An example is as below:

dummy
dummy
dummy
dummy
356.000 160.810 264.000 2.990
1.000 14.840 285.000 1.710
194.000 77.810 331.000 0.410

Basically, what it does in this case is
self.gr = np.loadtxt(fname=<filename>, skiprows=4)
which reads the NumPy array from filename with skipping the first 4 lines.

b). If you can export the data in the excel into an NumPy array, you can pass that to upf.polefigure.

2. I am not familiar with the EBSD data format you mentioned. There are two options yet as mentioned in a) and b). If you want to read the file, you'll have to parse the data into a form that is compatible with either a) or b).

I'm closing this issue but if you have more questions feel free to post them.
