Welcome to AITA book¶
The aim of this toolbox is to provide tools to perform data analyses on orientation maps.
An orientation map is a 2d image where a 3d unit vector is assigned at each pixel.
These analyses are built around the xarray
library and two accessors xarrayaita
and xarrayuvecs
.
All this documentation is built from jupyter-notebook and can be run using MyBinder by clicking on the “launch button”.
One classical application of this toolbox is the treatment of data obtained with the Automatic Ice Texture Analyzer (AITA) on thin sections of ice, quartz or snow.
Tutorials¶
Quick start : Short tutorial to plot colormap and pole figure from your dataset.
Crop data : Crop your data.
Misorientation profile : Plot misorientation profile along a line.
Mean grain : Compute the average orientation per grain. Requires the grain boundary segmentation data.
Misorientation angle distribution : Compute the misorientation angle distribution.
Grain boundaries segmentation : Perform grain boundary segmentation.
The xarray dependencies¶
aita
accessor : Axarray.Dataset
accessor for managing orientation data.uvecs
accessor :uvecs
for “Unit VECctor that are Symmetrical” management (UVECS). Axarray.DataArray
accessor.
Install the environment¶
If you want to install the python environment locally on your computer, we recommand using conda. You can follow this quick start to set-up conda.
Once conda is set-up you can install your environment using the environment.yml
file.
conda env create -n MyenvAITA -f environment.yml
To activate this environment use :
conda activate MyenvAITA
