Filtering (3D SEG-Y)
When you are confident that the headers have been appropriately mapped to their byte locations, you have the option of filtering the data to extract only a subset of traces from the SEG-Y files.
The top section of the Filters window provides an option to exclude all samples of a particular value when found at the top or bottom of traces. Samples in the middle of traces are not affected. By default, the value for this filter is set to '0'. This is especially useful in the 3D View, where these unwanted samples can obscure other data.
Additionally, you can also filter the data based on various trace headers. You can set the filter to include or exclude certain data. For example, to restrict the loading to a rectangular IL-CL patch (IL 1500–1700), use a series of Exclude filters:
- Exclude / 3D Inline / Less Than / 1500
- Exclude / 3D Inline / Greater Than / 1700
Multiple filters can be applied and the logical AND operation is used to combine these. That is, a trace must pass through all the filters to be included.
You can add more filters by clicking the Add Row icon and remove the filters by clicking the Remove Row minus icon.
When you have finished inserting filters, click Next to continue.
