Some GRBs are characterized by emission episodes occurring before the main event, called precursors. Their emission intensity is usually weaker than the GRB and is often comparable to (or slightly greater than) the background noise, making their detection difficult. We developed a code to automatically detect such precursors and applied it to a sample of 281 Swift/BAT GRBs. The identification procedure of precursor candidates uses a detection algorithm based on the wavelet transforms, and relies on an accurate study of the BAT background noise properties. A rigorous statistical approach is used for detection threshold settings and detection significance evaluation. We show the preliminary results of the analysis.
