Hi Bill-
Could you send a note to support-idv@xxxxxxxxxxxxxxxx with
a pointer to the file on an http or ftp server (or if it's
small, attach it to the message). We recently had another
inquiry about a similar problem and would like to check
into this further. For the other user, it appeared to
be a problem in the underlying netCDF library and using the
latest stable beta worked. You could get that at:
http://www.unidata.ucar.edu/software/idv/release/stable
and try it if you are daring. ;-)

Hi,
I just upgraded from v2.0 of IDV to v2.1. I have a netCDF file that works in
v2.0, but when I use it in v2.1 it does not. I am able to open the file, but
when I choose a variable for a contour plot I get error:
An error has occurred:
Couldn¹t get data
java.lang.NullPointerException
This gets followed by another error dialog box saying ³Unable to load field:
T2². The sequence gets repeated twice. Below is the header output for the
file if that helps anybody decipher this one.
Thanks for your help.
