Welcome to cRacker world!

About cRacker

cRacker has been programmed to automate standard normalization strategies of quantitative proteomic experiments. It simplifies the analysis of quantified peptide lists coming from various proteomic quantitation softwares. The applied normalization strategies are optimized for label free analyses of peptide intensities but also experiments using labeling approaches can be analyzed.


cRacker is written in R and uses TclTk for GUI. It is executed by calling R in batch mode using Rterm. For usage of cRacker no programming knowledge about R is necessary. cRacker will provide output of processed data in form of pdf and csv files.


cRacker can import text files containing lists of peptide intensities. cRacker calculates from these peptide intensities protein intensities according to your set parameters. The automatically applied multivariate statistics can help you to interpret your experiment immediately.
