Aperture selection through tem controller¶

This feature allows selection of aperture of TFS microscopes with automated apertures. The current implementation uses AutoIt Scripting and reads the configuration from c:\Program Files (x86)\myami\fei.cfg

Setup¶

compile autoit script¶

The script is pyscope/autoit/ApertureSelection.au3
Use AutoIt suite to compile it. Either 32 or 64-bit version works as far as I know.

Setup pyscope fei.cfg¶

Copy from pyscope/fei.cfg.template these lines to fei.cfg used on your scope. In standard installation, this should be "c:\Program Files (x86)\myami\fei.cfg"

Modify these settings according to your scope.

[aperture]
# Disable control of auto apertures if not working or not available
# not all versions of microscope software allows auto aperture control
# from scripting level.
USE_AUTO_APERTURE = False
# AutoIt Automation
