Hello Heiko-

The good news is that this bug is fixed in the next release.  The bad
news is that the next release is 2 months away. ;-)

We're looking to see if there is a way to tweak the file to get it
working in the IDV 1.2 release.

Thanks for bringing this to our attention.

I'm trying to read a netcdf file with IDV. The general structure of the file is quite similar to a lot of other files I've read, but this time, I get the following error-message:

133 is one of the dimension sizes. I tried to find out a bit more and got to this message:

The exception happens when I try to plot i.e. a Color Shaded Plan View of BC_ForestFires from

ftp://ftp.met.no/pub/emep/heikok/FF_BC2000_float.nc

It would be nice if somebody could have a look at the file and the problem since I would like to visualize the file.

Best regards,

Heiko
