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 ASI/TVIPS/Gatan cameras. Routines have been implemented for collecting serial electron diffraction (serialED), continuous rotation electron diffraction (cRED, aka 3D-ED / microED), and stepwise rotation electron diffraction (RED) data. For streaming cameras, instamatic includes a live-view GUI.

Instamatic is distributed via pypi and https://github.com/instamatic-dev/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
ASI CheeTah through serval-toolkit library
TVIPS cameras through EMMENU4 API
Quantum Detectors MerlinEM
(Gatan cameras through DM plugin [1])

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

See instamatic-dev/instamatic-tecnai-server for a TEM interface to control a FEI Tecnai-TEM on Windows XP/Python 3.4 via instamatic.

[1]: Support for Gatan cameras is somewhat underdeveloped. As an alternative, a DigitalMicrograph script for collecting cRED data on a OneView camera (or any other Gatan camera) can be found here.

Installation

If you use conda, create a new environment:

conda create -n instamatic python=3.11
conda activate instamatic

Install using pip, works with python versions 3.9 or newer:

pip install instamatic

OS requirement

The package requires Windows 7 or higher. It has been mainly developed and tested under windows 7 and higher.

Package dependencies

Check pypoject.toml for the full dependency list and versions.
