<DIV>I got the same seg fault that you got with your file. &nbsp;My guess is 
something is just not quite right with that file. &nbsp;The size of that 
&nbsp;domain should not be an issue. &nbsp;My ncl 6.1.2 is compiled from source 
so the precompiled binary theory affecting it is not the case. &nbsp;I am not 
sure what other things will spit out seg faults so Dennis will have to take 
lead.</DIV>
<DIV><BR></DIV>
<DIV>Sorry I couldn¡¯t be of more help,</DIV>
