Topic:
Padded dead traces after converting from IES to IESX

Description:
Seismic lines contain dead traces at the end of the lines after project
conversion.

Solution:
Check converted lines for interpretation posting beyond the end of the
seismic.

   - Seis2DV/3DV > post all interpretation

If required,interpretation can be deleted from IESX

   - DataManager  > Interpretation > Delete
   - Change area > Set range of dead traces/unrequired interpretation only

If all interpretation has been deleted from the padded traces the seismic can
be 'shrunk' back to contatin only live traces.

    - IESX_UTIL > Option 51 > Adjust Exploration Object Extent

This problem can be caused by shotpoint renumbering in IESX, after transfer of
seismic, but before transfer of interpretation or wrong interpretation being
converted.

For example, a line could exist in 2 different projects but with different
shotpoint range or numbering.  If a different project is selected to transfer
the interpretation to that from which the seismic is transferred traces will
be padded into the seismic to accomodate the shotpoint range of the
interpretation.
