How to Analyze your Data Using MATLAB

Once you’ve imaged your samples, you’ll need to use the MatLab software we provide to count your cells. The software approach improves both accuracy and speed with several built-in algorithms that aid in your counting and analysis. The video below discusses the software inputs and demonstrates how to use the software's features.
