Hi Todd-
Your student sent in a report last week, but we haven't had a chance to
look into it. We've been getting slammed with support so our answers
are a little less timely. It's on my list of reports to look at today.

To the list:
I have a student who is attempting to use IDV to calculate and display
Q-vectors using reanalysis data. In using some of the built in formulas
in the IDV, however, the IDV seems to gag on doing partial derivatives
of the NetCDF Reanalysis data, even though it works fine with model data
from the UCAR motherlode.
I'm attaching the error message below, and by my examination, it appears
that it might have to do with the way the coordinate system in the
NetCDF data is applied. Are there any users who have experience with
this matter that may be able to offer advice on an approach to solving
this issue?
I am also starting a support ticket, but thought that, since time is an
issue, I would try the collective expertise of the community as well.
Thanks for your time
Todd
