Use:

sugain trap=TRAPVAL < yourdata.su > yourdata_despiked.su

where TRAPVAL is the threshold value that you want to consider all
amplitudes to be greater than as noise spikes.

Hi, what is the value of amplitude's threshold? Is it calculated or conventional and How should be calculated in Seismic Unix?
