A procedure for reduction of spectral VLBI data has been developed. Based initially on the EVN pipeline procedure it was modified for processing maser experiments conducted on “Quasar“ VLBI network. AIPS is used to perform data reduction and ParselTongue module for Python is used for managing the process. This procedure performs standard steps needed for calibration and imaging of spectral data. In comparison with EVN pipeline Doppler correction was added and changes specific for spectral data was made in fringe-fitting and bandpass correction algorithms.
