Biological systems are highly complex and dynamic, whose behavior in response to changed conditions or perturbations cannot be predicted easily. Thus computational modeling can serve as a valuable analysis tool which allows an understanding of these systems that cannot be achieved with wet lab experiments alone. It can be used to gain a deeper understanding of the system or to answer more applied questions such as predicting drug targets. COPASI is a powerful environment for creating, editing, simulating and analyzing computational models. It provides a user-friendly GUI that is easy to use even by people who are not experts in the field. At the same time, its broad range of tasks makes it attractive for more advanced computational biologists. By using a scripting language in conjunction with COPASI, scientists can automate tasks such as parameter estimation, sensitivity analysis, optimization, and model fitting. They can also create custom scripts to perform complex operations or analyses that are not available in COPASI's GUI, such as model identification. Scripting languages can also facilitate the communication. documentation and reproducibility of computational models, by allowing scientists to share their code and results with others.Here we introduce BASICO, a simplified Python interface to COPASI. It provides a set of functions that allow to create, edit, simulate and analyze models in a more automated way. BASICO can be easily installed using: pip install copasi-basico.
