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.

Next, 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 a navigation point on the last trace.
