ict

The isotope correction toolbox (ict) is an efficient and easy-to-use (command-line) software tool that allows one to correct mass spectrometry data from isotope labeling experiments for naturally abundant stable isotopes. ict supports batch processing, considers the purity of the tracer, supports any labeling source and accounts for any number of isotopes. Its main advantage is its ability to deal with precursor ion fragmentation. Hence, ict can correct tandem mass spectrometry data.
