h1. 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

h2. Setup

h3. 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.

h3. 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.
