How to load navigation from SEGY trace headers without loading every point.

Description:
   
Loading every navigation point form trace headers can slow down a project.  
However, it may be the only navigation data available to load.

Here is a work around to load every nth navigation point.

Solution:
Load the seismic trace data normally without loading the navigation.
        Define Input Format - Loading Mode - Seismic.

Then, reload the same SEGY file but only use every nth trace. (Example n=10)  
        Define Input Format - Loading Mode - Stations

Note: The nth trace number you choose may be such that due to the division of 
the total number of traces, it may not get the navigation point of the last 
trace.
