Greetings,
I've been enjoying creating graphical plots of my netCDF
formatted data using NCL--very nice interface. Recently,
however, I've discovered that my installation of NCL apparently
won't read files larger than 2GB, this in spite of the fact
that I have compiled the netCDF libararies to support large
files. I can successfully read and write large netCDF files
with gcc, pgf90, and Perl.
I am running RedHad Linux:
Linux zephyr 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 i686 i386 GNU/Linux
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
pgf90 version 5.1-3
When I try to read a large file with NCL I get the following message:
%ncl contour_HCHO.ncl

fatal:_NclCreateFile: Requested file does not exist as
(/data/ASAP/output/basetest/airshed.2.nc) or as
(/data/ASAP/output/basetest/airshed.2), can't add file
fatal:Either file (a) isn't defined or variable (HCHO) is not a variable in the
file
fatal:Execute: Error occurred at or near line 70 in file contour_HCHO.ncl
Here are lines 69-70 of the script:
69 conc = a->HCHO*1000.
70 time = a->time
This identical script does work for files smaller than 2GB. No single
variable exceeds 2GB.
Any help is greatly appreciated.
