1. In the interactive mode of SEGCLASSLAYER, I can extract the amplitude and phases of equator and cannot explore interactively the other desired layer lines (as shown in the SPRING publication Fig 3.) How to explore the other layer lines interactively? I tried to click the next button in the gui window and it did not work.Zoom-in to very high levels until you have large pixels - then press the middle mouse button and a new tab with the respective layer line will open.
