We present a data analysis procedure which aims at searching for gravitational-wave transients in coincidence with highenergy neutrinos. In this procedure, the time and direction of the high-energy neutrinos are used to define the time interval and sky region where the available gravitational-wave data will be searched. The pipeline essentially relies on coherent WaveBurst (cWB), an all-sky all-time search pipeline for gravitational-wave bursts. Changes have been made in order to restrict the production of cWB events consistent in time and direction with the neutrino candidates. The pipeline allows the analysis of thousandths of neutrino candidates in a bandwidth ranging up to several kHz with standard computing ressources. A comparison with earlier analyses is presented using a set of simulated neutrino candidates and time-shifted gravitational-wave data.
