Hello everyone,

I have a bit of a dilemma that I hope you can help me with.  My netCDF
data is composed of several fields, each of which is one variable of
oceanographic data that is being measured for a given area of the ocean.
Each of these fields is composed of data, positions, connections, and data
statistics components.  Each of these components then has attributes.
When I import data from a file, what I end up with is a group consisting
of all of these fields.  Depending on where I decide to start and end, I
can decide to import the data from just one given day, or any group of
days up to the entire set of days.  I can also decide to import just one
given field from the group.

My problem is this: if I import the fields individually, depending on the
variable chosen with a selector interactor, I have to manually write out a
string list of the variables in the file to get the choices to show up in
the selector list.  But if I do that, it means that if I import a
different file that has different fields, the selector list is no longer
appropriate for the data.

However, if I import all the fields at once, the selector list can detect
the names of the fields in the group and give an appropriate list of
options.  But then, I don't know how to sort these fields based on the
characteristics of the data, because Inquire only seems to be able to work
on an entire group at once or a single field.  This means that if I have
some fields that have vector data and some that have scalar data, I have
no way to make sure a selector list has only the appropriate variables in
it.  I would like to be able to have a selector for variables
for which I would like to show glyphs by somehow taking out a subset of
all the variables in a given file.  How can I have both automatically
detected field names and be able to select fields from a group of imported
fields based on a specific characteristic of the fields?

I hope this makes sense.  I would really appreciate some help with this;
perhaps there is some module I missed that I could be using to get the
desired results.  Let me know if you need more clarification.  Thanks.
