In the digital age of education, OpenMCR emerges as a ray of hope for educators and institutions looking to economize on grading tools. This free software stands as a competent alternative to expensive Optical Mark Recognition (OMR) systems, making it accessible and user-friendly for everyone from teachers to students.

Downloading and Installing OpenMCR

Setting up OpenMCR is straightforward. Follow these steps to get started:

Windows Installation

• Download the latest .exe file from the releases page.
• Double-click the downloaded file to install the software.
• Check your Start menu for a new application shortcut.

Running Without Installation

• If installation isn’t an option, download the ZIP file from the releases page.
• Extract the ZIP file to any folder on your computer.
• Run the main.exe file without needing administrator privileges.

Running From Source (CLI)

For Developers or Advanced Users

Do you want to customize the software? Here’s how you can run it from the source files:

• Clone the repository using Git or download the latest Source code (zip).
• Open a terminal or command prompt in the extracted directory.
• For Mac users, ensure that Tkinter is up-to-date.
• Run pip3 install -r requirements.txt to install necessary dependencies.
• Execute python3 src/main.py for command line or python3 src/main_gui.py for the graphical interface.

Note: If you experience any graphical issues on MacOS, uninstall Python, install Tkinter, and reinstall Python using Homebrew, as per guidance in the Apple StackExchange.

On Linux, if you see an error related to opencv or tkinter, you can resolve it by running sudo apt-get install python3-opencv python3-tk.

Using Codespaces

For those engaged in development, an environment is available through Codespaces. This allows you to run the GUI in your browser with the desktop password set to vscode.
