After I loaded a 3D seismic volume, on which I had to define its bounds manually (inline and crossline), at the moment to look seismic sections -whatever you want to watch, i.e. inline or crossline section-, these appears blank. But data are there! Few instants later, I realized that amplitudes range values exceeds the typical or common values. In this case, range varies from 6.25e+034 until -6.25e-034! I think if can modify this range perhaps the seismic volume can be watched. My question at the end is: how can I modify the amplitude range value in order to can watch the 3D seismic volume? Thanks in advance for your comments.
