Be
prepared for big changes with the next release!
CDAT 4.3 will be
the last CDAT version
with the Numeric module. From the new version 5.0
and on, we will be only supporting the NumPy module and Python version
2.5.
Both CDAT 4.3
and 5.0
will only compile with the Python 2.5+ versions.
Also, please
note, that the Numeric module with Python 2.5 will not compile on the
64 bit
platform.
New
Modules
Because of the
changes coming with the new NumPy, the CDAT
5.0 will have new modules cdms2
and MV2 and the old cdms and MV modules
will be deprecated. We will be supplying the authomatic
conversion program that will help you with the transition from the
pre-CDAT 5.0 to the post CDAT 5.0 programming with the new
modules.
We are
excited to introduce new TrueType
fonts into CDAT.
The font
number is now
not limited to 9, but it is unlimited.
By default the fonts are loaded from your PCMDI_GRAPHICS
directory. But you can also add you own fonts dynamically when running
the application.
Here are the default fonts distributed with
CDAT and their
correspondent
numbers:
The CDAT Demo have been updated and
improved. Many new tutorials have been added. Please do check it up.
To start it, at the Xterm prompt, type:
%cdatdemo
You can
see a whole range of demo scripts and you can run them in the
PyDebugger. It's an excellent way to quickly learn about CDAT's
capabilities and pick up new tricks.
There is
always a lot of questions about the time axis and how to properly
understand it and convert between different time representations and
different time units, in order to for example analyse two datasets with
different time representation.
We are
providing here the tutorials on the time axis and different ways of
working with it.
