Re: NetCDF metadata and selected data variables
Hi Brian:
I answered your previous post, but your personal email bounced. Hopefully you're reading this group
email.

Hi All,
I posted the same question last Friday, but I didn't get any response so
I am going to rephrase it now that I have explored the problem myself a
little more.
My program is applying subset and reduction criteria to a netcdf file
and outputting another netcdf file. I am also allowing the user to
choose which data variables they get in the output. The problem I am
having is that when I write out the metadata I have conflicting
requirements for how that metadata will look. How do I reconcile
differences in the subset and reduction criteria which has ben applied
to the data variables. This does not seem to be posible given the
structure of the netcdf file.
When looking closely at the metadata which is written to the output
netcdf file I can see that the length of each coordinate variable is
set. This doesn't make sense when I am subsequently gong to write out
data variables which either don't use one of the coordinate dimensions
at all, or have different lengths for the coordinate variables.
I suspect I am trying to do something that the netCDF file format does
not support.
Thanks
Brian
