Quantitative Parasitology on the Web (QPweb)




After a major breakdown between 1st of June 2021 – 4th of July 2021, now we are glad to inform you that QPweb is fully functional again. Find it here:




Quantitative Parasitology 3.0


This software provides statistical tools to analyze and compare the highly aggregated (right-skewed) frequency distributions exhibited by parasites. However, it can handle only monotypic (single species) infections.  


WARNING! This software is not up to date, and we recommend using it only as a secondary choice. Also, this version's "aggregation indices" module does not work under Win10, only under former versions of Windows (like Win7).
