Re: help

Dear Mohamed,

Thanks for providing the script. Do you know which line it is seg faulting on?

Also, which version of NCL are you using?

You can usually get this information by temporarily commenting the "begin" and "end" lines, and
running your script with the "-x" option:

   ncl -x GRID-Interpolation.ncl

This will cause every line to be echoed back to you as it is executed, so then you should be able
to see where it seg faults.

It's possible that the seg fault is caused because of running out of memory. It would be helpful to
call "printVarSummary" on some of your variables.
