MAPIT (Material Accountancy Performance Indicator Toolkit) is a Python package designed to aid in safeguards analysis of bulk materials. The inherent flexibility is designed to allow safeguards practitioners ask the "what if?" questions while providing transparency into commonly employed statistical tests.
MAPIT provides both a graphical user interface (GUI) and an application program interface (API). The API can be used with other popular Python libraries to extend functionality and integrate with other analytical workflows.
⚠️ The MAPIT API has breaking changes in v1.40.0-beta. The API was modified to accommodate a parallel processing capability. See API documentation for more details.

🚧 MAPIT IS IN BETA 🚧
You may notice various bugs and errors. Help contribute to this project by reporting them through our issue page.
We aim for biannual release updates for MAPIT, but if you have immediate needs that need to be addressed, please open an issue or contact us directly.
MAPIT does not yet have a PyPI or Conda repository, so it must be installed manually. Download the source code from here and install the requirements via either the requirements.txt or requirements.yml. Once the requirements are installed, use the GUI by launching MAPIT_main.py or access the API by ensuring proper pathing.
To streamline this process, we have included both Windows-based and Unix-based installers for those new to Python. These can be found in the windows_scripts and unix_scripts folder respectively.
After installation, the MAPIT GUI can be launched using MAPIT from terminal after installation. Examples of the API can be found in the API_examples folder. We have included an exemplar dataset (located in a separate MAPIT-tools repository) and several tutorial exercises to help you get started, which can be found here
We have included documentation for several guided exercises as well as the API, both can be found here
