Hi Frances,
As Oliver said, the 2.2 version of the stuff is very much not compatible
with typhon.
I am the one that made the mess here with the catalog so I should add a few
more words. Since the typhon IO for catalogs was basically a full
reimplementation of the ARTS stuff, it has always lagged behind because it
was not my focus. It only ever worked for things that I personally wanted
it to work for and quickly broke as new features were introduced into ARTS.
With the latest version of ARTS, you get a python interface out-of-the-box
when you build ARTS called "pyarts". With pyarts, you get
"pyarts.classes", which gives a way to use every ARTS class directly in
python. It is a very basic interface at this point, but you can use all
the IO capabilities of ARTS, including reading ARTSCAT4 catalogs. It is
still new and a bit cumbersome, though there is
"pyarts.classes.from_workspace()" that can take any ARTS workspace variable
and map it for you in python [not copy, map, so all changes you do to the
map are there if you use more ARTS methods]). The ARTS IO already remaps
everything to the ARTS data format and you can then take it from there with
whatever you want to use the data for.
With hope,
//Richard
