Need help using the IPTS selector?

    with h5py.File(o_event.input_nexus_file_name, 'r') as nxs:
    o_event.x_array = np.array(nxs['events']['x']
    o_event.y_array = np.array(nxs['events']['y']
    o_event.tof_array = np.array(nxs['events']['tof_ns']

The higher the percentage, the longer it will take to rebin the data. This time will of course depend on the number of events you have to start with.
