The Open Source Microscopy Project "µManager" at the Vale laboratory at UCSF (funded by the NIH) aims to provide a universal, flexible and low-cost software platform for automated microscopy. In order to provide lasting value and real benefit to a wide community of researchers, we have taken the approach of building a self-contained software product, with quality and ease-of-use standards equal to commercial software. At the same time µManager project leverages other Open Source tools and components to the maximum extent possible.
