What is Comstat2? Comstat is a program that analyzes image stacks of biofilms recorded by confocal microscopes. It can extract a number of quantitative parameters from biomass to fractal dimensions. The program does not contain any statistical calculation methods. Comstat was developed by Arne Heydorn and Prof. Bjarne Ersbøll in 2000 [1] as a MATLAB© script and has for many years been one of the preferred tools for biofilm quantification. In 2008 Martin Vorregaard ported and expanded the software [2] so it would run independently from MATLAB© but instead to utilize the public domain software Java© and the Image processing environment ImageJ (http://imagej.nih.gov/ij/) with the add-on package LOCI Tools (http://loci.wisc.edu/software/bio-formats). Comstat v. 2.1 is the latest build of this ImageJ plugin and this version was compiled and released July 1st 2015. How to get Comstat2 Please follow this link to go to the sign up page.

How to correctly cite the use of Comstat2 When publishing work which includes analyses made by Comstat2 we request that you will use these three references: Heydorn, A., et al., Quantification of biofilm structures by the novel computer program COMSTAT. Microbiology, 2000. 146 ( Pt 10): p. 2395-407. Vorregaard, M., Comstat2 - a modern 3D image analysis environment for biofilms, in Informatics and Mathematical Modelling. 2008, Technical University of Denmark: Kongens Lyngby, Denmark www.comstat.dk We are in the process of making a paper about Comstat2 which will replace these. When that happens the information on this page will be updated and a news bulletin will be sent to the mailing list.
