| + | ===== Loading and plotting grain orientations in MTeX, in an inverse pole figure, and with colors! ===== | ||
| + | |||
| + | Here is an example of a script that will load these orientations and plot them in a inverse pole figures. The example is for olivine and can be adjusted to your needs. Grains are assigned a color based on the ODF intensity for their orientations. | ||
