24.06.2025 Calopy - a novel open-source tool for the analysis of energy metabolism

Energy metabolism is a fundamental process by which living organisms convert nutrients into usable energy. Indirect calorimetry is a widely used technique for measuring energy metabolism in both humans and animals. At its core, indirect calorimetry non-invasively tracks oxygen consumption and carbon dioxide production. A team of bioinformaticians and researchers led by Helmholtz Munich, including Dr. Carola Meyer from the Institute of Pharmacology at Marburg University, have recently developed a novel web-based open-source platform for the intuitive and comprehensive analysis of indirect calorimetry data. Calopy is a free, open-source, web-based application that is accessible online at https://www.calopy.app. It provides a flexible and robust framework to handle and analyse indirect calorimetry data, which can be easily extended with novel features and methods.
