Determine the Format of a SEG-Y File

If no external documentation or other information is available, use the tools in the Explore menu (Text Header, Binary Header, TraceViewer) to examine the contents of the SEG-Y file. The information stored within the file should allow you to read and display it. SEG-Y files are also frequently shipped with a loadsheet describing the data.

If the SEG-Y Reader doesn't automatically detect the correct machine format (byte order) and trace data format, use the TraceViewer to examine the wiggle traces using the possible formats. It is generally pretty obvious which choice is correct. You may then specify the correct format in the SEG-Y Disk format topic in SEG-Y Reader.
