A python package for working with crystal orientations in transmission electron microscopy

Project description

# pycotem

pycotem is a python package for working with crystal orientations in transmission electron microscopy. It provides 6 GUI tools to:

  • determine orientation from diffraction patterns: `diffraction`
  • determine orientation from Kikuchi patterns: `kikuchi`
  • work with stereographic projections: `stereoproj`
  • determine interface normal and direction from images: `interface`
  • determine orientation relationship and misorientation between two crystals: `misorientation`
  • display crystal projection on a plane and draw dichromatic patterns: `crystal`

## Getting Started

### Prerequisites

pycotem relies on `python3` with `numpy`, `pillow`, `matplotlib` and `pyqt5` (for GUI) packages.

### Installing and running

pycotem can be installed with pip: `pip3 install pycotem` Run `python3 -m pycotem.xxxx` for the different tools: `stereoproj`, `diffraction`, `kikuchi`,```misorientation```,```interface``` and `crystal`.

### Examples

Image files and setting parameters are provided in the `test` directory in the github repository for testing `diffraction`, `interface` and `kikuchi`.
