Import Wizard - Trouble

Empty ASCII, Binary or Trace Header Summary

• Are you sure this is a SEG-Y file?
• Check other Import Wizard tabs for usable information. Don't forget to view header contents. (Click <View Binary Header> on the Binary Header tab. Double-click on individual traces in the summary list of the Trace Header tab. Look at several traces.)
• If you can view trace samples on the Trace Data tab and your data is recognizable in the Preview window, you can work around missing header information. Try manually entering binary values on the Binary Header tab and then selecting a coordinate import method that does not read information from the trace headers.

Is the Trace Header Information Correct?

Trace Header Values

If you are missing some or all of the trace header information, you can still import your data.

Data Values Below Zero

WinPICS does not support data with a max value below one. Before loading, you should scale up any SEG-Y file values < 0 to at least 1.

What do you want to do?

• Find out why you don't have 2D shotpoints in the trace headers
• Find out why you don't have 3D in-line/cross-lines in the trace headers
• Find out why you don't have x/y's in the trace headers
