We introduce CNTb, a set of scripts allowing a batch inversion of series of photon correlation spectroscopy data files via CONTIN with a single command line. In addition CNTb allows the fitting of the resulting distribution of relaxation times by a set of log-normal distributions and calculates mean values and standard deviations for their parameters over the data set. CNTb proves to be a very useful tool when a large number of experiments is needed to test the reproducibility and the reliability of CONTIN output in difficult experimental conditions, e.g., when the signal to noise ratio is low.
