    pXtract creates .DTA¡¢.MGF and .MS2 input files directly from Thermo Scientific .raw LC-MS/MS data files.

     For each fragmentation spectrum, pXtract first attempts to determine the precursor charge state using the information recorded in the scan header. If this information is available, only a single spectrum is written using that precursor charge. If it is not available (could not be determined by the instrument firmware), two spectra are generated for +2 and +3 state, respectively. The precursor [M + H]+ value is written with its corresponding charge state, followed by every centroid m/z and intensity pair from the MS2 scan.

    pXtract can automatically distinguished between CID¡¢ETD and HCD generated spectra, allows the user to export the spectra into different files for the future work.

    Both English and Chinese version are available.

    pXtract is free to use, download and try it: pXtract
