[Shake-dev] bug in "grind.conf" "strictbounds" parameter

[Bruce Worden]

Hi Howard, others,

This was a bug that Georgia reported earlier, and it has been fixed  
in V3.1 of ShakeMap -- so people who have upgraded will not need to  
do anything.  For those of you with earlier versions, the fix that  
went into "grind" was to change the line:

      @bigbound[W,S,E,N] = split /\s+/,$strictbound;

to:

      @bigbound[W,S,E,N] = split /\//,$strictbound;

Just search on the string "strictbound" until you find the line in  
question.

I don't believe that using a space-separated list will actually pick  
up any but the first coordinate, with the rest probably taking on  
default values.  So while it may appear to work, it likely won't give  
you the exact coordinates you specify.
