Which SEG-Y formats are supported by the SEG-Y Loader?

SEG-Y is the only supported format for transferring 2D and 3D trace data into Insight.

The DUG SEG-Y Loader supports both SEG-Y Revision 0 (1975) and Revision 1 (2002).

The trace data format must be specified in the Data Sample Format Code. The codes are:

1 = 4-byte IBM floating-point

2 = 4-byte, twos complement integer

3 = 2-byte, twos complement integer

4 = 4-byte fixed-point with gain (NOT SUPPORTED)

5 = 4-byte IEEE floating-point

6 = Not currently used

7 = Not currently used

8 = 1-byte, twos complement integer

Insight does not support SEG-Y in 4-byte fixed-point with gain format.
