Re: comparison failes for Yearly averaged data sets


I have solved your problem by fixing a bug in Ferret.pl.  I made changes
based on our most recent version of Ferret.pl.  This most recent version
will not work with the LAS release you have but you should be able to
use the results of 'diff' to make the appropriate changes to your
version of Ferret.pl.

I've attached a 'diff' page from our web interface to CVS.  The line
numbers won't match up exactly but I hope you can find the points to
insert/delete pretty easily.  The newer version is on the right hand


Let me know if you get stuck.
