Carlos, I haven't played with this data specifically, but I think there 
are to possibilities.  First, try byte switching the data from big to 
little endian (or vice versa) when you import it.  If that doesn't 
work, I am guessing that null values are handled as -32767, and 32768.  
Use r.null to replace these values with null, then check out your data.

What happens if a big asteroid hits Earth? Judging from realistic 
simulations involving a sledge hammer and a common laboratory frog, we 
can assume it will be pretty bad.
