[RegCNET] RegCM4 NetCDF output not-fully compatible with GrADS

Dear ALL,

I am having problems with the NetCDF output of RegCM4 and its use on GrADS.
I used the following command..

./rcm2netcdf -a -v p -t 199001 -e 200001 regcm.in
The terminal window showed the following...
Value not found : i_band
Assuming non tropical BAND run.
Found Atmospheric data ATM and processing...................

... and obtained a 46 GB NetCDF file. I opened it with GrADS for
postprocessing, but when I displayed the data, the image showed strange
lines instead of the map. And I cannot understand how this is so.

I had a similar problem with data from ESRL, but that was a result of
processing and I solved it by downloading the original unprocessed files.
Since there was no processing other than the production of the nc file, I
cannot understand what the problem is.

I was hoping that somone might have encountered a similar problem before and
could help me figure this out.

Regards,

James Ciarlo`
