Simple seismic processing pipeline

The next example controls a simple processing job using SEP software. A dialog box is used to input a file name. This file is read into a bandpass filter program, then converted to one byte per sample (for display) by the program Byte, then plotted. Sliders are used to specify the cutoff frequencies for the filter, and for the percentile of the filtered data that is clipped to the maximum intensity in the float to byte conversion.

button={ label=GO 
  action="Bandpass flo=$flo fhi=$fhi phase=$phase < $file > band.h ;            Byte pclip=$pclip < band.h | Ta2vplot | Xtpen &"
}
dialog={ name=file label="input file" value="Dat/wz.25.H" }

  }
