A graphical tool for selecting points for analysis on an SEM image
You can download the TACtool application here:
Instructions for using the application can be found here.
TACTool was initially developed within the British Geological Survey by:
- Connor Newstead
- Dan Sutton
- Declan Valters
- Leo Rudczenko
- John A Stevenson
The original idea was by Connor Newstead and Matt Horstwood.
Check out the repository and install dependencies using Anaconda.
conda env create -f environments/windows-environment.yml
conda activate tactool-windowsconda env create -f environments/macos-environment.yml
conda activate tactool-macosNote: Both environments have been generated using environments/unversioned-environment.yml.
To run the program, first you need to setup your Python path.
$env:PYTHONPATH="."export PYTHONPATH=.Then you can run the program with:
python tactool/main.py --devThe --dev flag starts the application in developer mode, with a test image
pre-loaded into the GraphicsView.

Ensure you have setup your Python path. Then you can run the tests with:
pytest -vv test/pyinstaller --name="TACtool" --windowed --paths=. --onefile tactool/main.py
Run the above code and a .spec file and dist/ build/ directories will be created.
