Re: Do not need to reverse?

Hi Yi,

I think this might be a bug.

To help us debug: If you just have a single call to a gsn_csm_xxxx
routine, can you set:

    res@gsnDebugWriteFileName = "latbug"

rerun your script, and then send me the "latbug.ncl" and "latbug.nc"
files?

If "latbug.nc" is too big to send, then see:

http://www.ncl.ucar.edu/report_bug.shtml

for where you can put the file.

Thanks.
