Python program for automated electron diffraction data collection

Project description

build PyPI DOI

Instamatic

Instamatic is a Python program that is being developed with the aim to automate the collection of electron diffraction data. At the core is a Python library for transmission electron microscope experimental control with bindings for the JEOL/FEI microscopes and interfaces to the gatan/timepix/tvips cameras. Routines have been implemented for collecting serial electron diffraction (serialED), continuous rotation electron diffraction (cRED), and stepwise rotation electron diffraction (RED) data.

Instamatic is distributed as a portable stand-alone installation that includes all the needed libraries from: https://github.com/stefsmeets/instamatic/releases. However, the most up-to-date version of the code (including bugs!) is available from this repository.

Electron microscopes supported:

  • JEOL microscopes with the TEMCOM library
  • FEI microscopes via the scripting interface

Cameras supported:

  • ASI Timepix (including live-view GUI)
  • Gatan cameras through DM plugin
  • TVIPS cameras through EMMENU4 API

Instamatic has been extensively tested on a JEOL-2100 with a Timepix camera, and is currently being developed on a JEOL-1400 and JEOL-3200 with TVIPS cameras (XF416/F416).

A DigitalMicrograph script for collecting cRED data on a OneView camera (or any other Gatan camera) can be found at dmscript.

Installation

pip install instamatic

Alternatively, download the portable installation with all libraries/dependencies included: https://github.com/stefsmeets/instamatic/releases/latest. Extract the archive, and open a terminal by double-clicking start_Cmder.exe.
