4.3.10.1.3 SEG-Y Examiner

SEG-Y Examiner can be launched by pressing on icon in Import SEG-Y Data window. SEG-Y Examiner allows to check essential information about the data by inspecting text, binary and trace headers as well as plotting seismic traces for QC. It is recommended to use this tool to check your SEG-Y import set-up and adjust it if needed.

SEG-Y Examiner can stay open during import.

File header information:

Save textual header to a file.

Trace header information:

Use the lateral scroll bar at the bottom to locate the headers with changing values. Those might be trace numbers, crossline numbers, offsets, coordinates etc. Inline numbers are often written to the bytes preceding crosslines. Most 3D data is inline sorted, therefore choose sufficient number of traces to examine (several times more than the number of crosslines per inline) in order to see the increasing inline numbering.

Display traces: It is strongly recommended to always view examined traces in the 2D viewer.

Show histogram of sample values.
