ScySeqTools is a suite of software: encoder and analyser

ScySeqTools

ScySeqTools is a Python toolkit for coding and analysing behaviours. It currently provides two command line launchers:

• scyseq-encoder
• scyseq-analyser

Requirements

• Python 3.9 or newer
• Hatch, used to create and manage the development virtual environment
• VLC 64-bit, required by the encoder through python-vlc
• tkinter
  • Windows: included with the standard Python installer
  • Ubuntu/Debian: sudo apt install python3-tk
  • macOS: install Python from python.org if tkinter is missing

On Windows, install 64-bit VLC from:

https://www.videolan.org/vlc/download-windows.html

After installing VLC, this file should exist:

Test-Path "C:\Program Files\VideoLAN\VLC\libvlc.dll"

Starter Setup

Clone or download the project, then open a terminal in the project folder. On Windows, use PowerShell; on macOS or Linux, use your usual terminal.

cd path/to/scyseqtools

Replace path/to/scyseqtools with the folder where you cloned or downloaded the project.

1. Check Python

python --version

You should see Python 3.9 or newer.

2. Check Whether Hatch Is Installed

hatch --version

If your terminal says hatch is not found or not recognized, install it:

python -m pip install hatch

Then check again:

hatch --version

3. Create and Enter the Hatch Environment

From the project root, run:

hatch shell

Your prompt should now start with something like:

(scyseqtools) ...

That means you are inside the ScySeqTools virtual environment.

4. Install ScySeqTools in Editable Mode

Inside the Hatch shell, install the current project:

python -m pip install -e .

The -e option means "editable": Python imports ScySeqTools directly from this source folder, so local code changes are picked up without reinstalling every time.

5. Verify the Install

python -m pip show scyseqtools
python -c "import scyseqtools; print(scyseqtools.__file__)"
python -c "import scyseqtools.encoder.main; print('ok')"

If the last command prints ok, the package import works.

Run ScySeqTools

Inside the Hatch shell:

scyseq-encoder

or:

scyseq-analyser

The encoder opens a graphical interface and asks you to choose a working directory. ScySeqTools expects or creates media and data folders inside that working directory.

User Configuration

On first run, ScySeqTools Encoder creates an editable config file in the standard per-user config folder for your operating system:

Windows: %APPDATA%\ScySeqTools\Encoder\config.ini
Ubuntu/Linux: ~/.config/ScySeqTools/Encoder/config.ini
macOS: ~/Library/Application Support/ScySeqTools/Encoder/config.ini

The app loads configuration in this order:

1. Bundled defaults inside the package or .exe.
2. The user-editable OS config file shown above.
3. A config.ini in the selected working directory, if present.

That means users can change global defaults in their user config folder, and a specific project can override them by placing its own config.ini in the project working folder. The last selected working directory is remembered in:

Windows: %APPDATA%\ScySeqTools\Encoder\cwdfile.ini
Ubuntu/Linux: ~/.local/state/ScySeqTools/Encoder/cwdfile.ini
macOS: ~/Library/Application Support/ScySeqTools/Encoder/cwdfile.ini

Encoder Window Layout

By default, the encoder opens with the classic single-window layout. To split the encoder into separate Information, Control, and Coding framework windows, add this to the AppData or project config.ini file:

[application]
encoder_layout = detached

Download Applications

GitHub Actions builds downloadable encoder and analyser applications for Windows, Ubuntu, macOS Intel, and macOS Apple Silicon. Each workflow run uploads temporary build artifacts:

ScySeqTools-Encoder-windows-x64-<tag>.zip
ScySeqTools-Encoder-ubuntu-22.04-x64-<tag>.tar.gz
ScySeqTools-Encoder-macos-x64-<tag>.zip
ScySeqTools-Encoder-macos-arm64-<tag>.zip
ScySeqTools-Analyser-windows-x64-<tag>.zip
ScySeqTools-Analyser-ubuntu-22.04-x64-<tag>.tar.gz
ScySeqTools-Analyser-macos-x64-<tag>.zip

The packaged encoder apps do not bundle VLC. Install VLC on the target machine before running the encoder. On Windows, confirm this file exists:

Test-Path "C:\Program Files\VideoLAN\VLC\libvlc.dll"

macOS builds are not Developer ID signed or notarized yet, so users may need to right-click the app and choose Open, or allow it from macOS Privacy & Security settings.

Build Applications Locally

From the project root, install build dependencies:

python -m pip install -e ".[dev,build]"

Then run the spec for your OS:

# Windows
pyinstaller --clean --noconfirm packaging/pyinstaller/scyseq-encoder-windows.spec
pyinstaller --clean --noconfirm packaging/pyinstaller/scyseq-analyser-windows.spec

# Ubuntu/Linux
pyinstaller --clean --noconfirm packaging/pyinstaller/scyseq-encoder-linux.spec
pyinstaller --clean --noconfirm packaging/pyinstaller/scyseq-analyser-linux.spec

# macOS
pyinstaller --clean --noconfirm packaging/pyinstaller/scyseq-encoder-macos.spec
pyinstaller --clean --noconfirm packaging/pyinstaller/scyseq-analyser-macos.spec

Run Tests

Inside the Hatch shell:

python -m pytest tests

Build the Documentation

The documentation is built with Sphinx.

First enter the Hatch environment from the project root:

hatch shell

Then navigate to the docs folder and build the HTML files:

On Windows:

cd docs
./make.bat html

On Linux/Mac:

cd docs
make html

The generated HTML documentation will be available in docs/build/html/. Open docs/build/html/index.html in your browser to view the documentation.
