Introduction

Pytemscript is a Python package designed around standard and advanced scripting interfaces of Thermo Fisher Scientific and FEI transmission electron microscopes. The functionality is limited to the functionality of the original COM scripting interfaces. For detailed information about TEM scripting see the documentation accompanying your microscope.

The pytemscript package provides a client API to connect both locally and remotely to the microscope PC. Currently, the minimum supported Python version is 3.4, so you should be able to control TEM instruments operating Windows XP or newer OS. This allows us to support scripting on a wide range of TEM platforms including Tecnai, Talos and Titan.

This is a GPL fork of the original BSD-licensed project: https://github.com/niermann/temscript New changes and this whole product is distributed under either version 3 of the GPL License, or (at your option) any later version.

Quick example

Execute this on the microscope PC to create an instance of the local Microscope class:

from pytemscript.microscope import Microscope
microscope = Microscope()

Show the current acceleration voltage:

microscope.gun.voltage
300.0

Move beam:

shift = microscope.optics.illumination.beam_shift
shift += (0.4, 0.2)
shift *= 2
microscope.optics.illumination.beam_shift = shift

Take an image:

image = microscope.acquisition.acquire_tem_image("BM-Ceta",
                                                 size=AcqImageSize.FULL,  # <-- see enumerations
                                                 exp_time=0.5,
                                                 binning=2)
image.save("img.mrc")
