AngioQuant is an automated image analysis tool for quantification of angiogenesis. It is designed for in vitro angiogenesis assays that are based on co-culturing endothelial cells with fibroblasts. AngioQuant provides quantitative and repeatable measurements of the lengths and sizes of tubule complexes as well as the numbers of junctions (branching points) in the tubule complexes. The resulting quantification data are saved in the comma separated values (CSV) format. The CSV files can be easily opened in a spreadsheet program such as Microsoft Excel®.
AngioQuant requires an installation of the MCR libraries, a MATLAB® runtime component provided by The MathWorks, Inc. The MCR libraries can be downloaded from this site. Alternatively, AngioQuant can be run under MATLAB 6.5 (R13) or higher with the Image Processing Toolbox. Instructions on the installation and use of AngioQuant can be found in the User's manual. Information on the underlying image processing methods can be found in the original manuscript. The set of test images that is used in the manuscript is also available for download on this site. If you would like to receive notifications of future updates, please send us your e-mail address.
The standalone version of AngioQuant is available for Microsoft Windows based systems. The file AngioQuant.zip includes the necessary files. If you have not installed the MCR libraries, you need to also download the file MCRInstaller.exe. The MCR libraries must be installed before installing AngioQuant. Installation instructions for AngioQuant and the MCR libraries can be found in the user's manual and in the README.txt file.

Note: there are reports saying that installing the MCR libraries fails on Windows 2000 based systems. Under Windows XP there seems to be no problems. More information on this issue will be posted here when it is available.
The toolbox version of AngioQuant can be run on any platform for which MATLAB® is available. An installation of MATLAB 6.5 (R13) or higher with the Image Processing Toolbox is required. Installation instructions can be found in the user's manual and the READMETBX.txt file.
