CERR (pronounced 'sir'), stands for Computational Environment for Radiotherapy Research. CERR is a software platform for developing and sharing research results using radiation therapy treatment planning information. CERR is written in the widely-used Matlab language (version 6.1 or later), allowing for low-cost development of visualization and analysis tools. CERR is actively supported by the Division of Bioinformatics and Outcomes Research, Dept. of Radiation Oncology, Washington University School of Medicine, and has a wide variety of dose, imaging, and structure analysis and comparison tools. CERR is free to use for research projects. Clinical use on individual patient cases is prohibited.
DREES(Dose Response Explorer System) is an open source tool for TCP and NTCP modeling, evaluating robustness of models and exploratory and prediction data analysis.
