Silva£¬</FONT></FONT>
<DIV> </DIV>
<DIV>I am a grads user. As your introduction, I am very interested in PyGrADS.
But I have never known about Python.</DIV>
<DIV>Today I have a try. The installation is easy. There are some question about
the PyGrADS.</DIV>
<DIV> </DIV>
<DIV>1. PATH:</DIV>
<DIV>The install package didn't add the Python PATH to the OS search PATH
automatically.</DIV>
<DIV>I added "C:\Python25;C:\Python25\Lib\site-packages;C:\Python25\Scripts" to
the end of system's PATH. I don't know whether it is enough.</DIV>
<DIV> </DIV>
<DIV>2. "From your OS the command line enter: % pygrads -h"</DIV>
<DIV>The windows command line can just run executable file such as .exe and
.com. But I cannot find the executable file about pygrads <IMG
src="cid:__0@Foxmail.net">. The only way is double-click the file "pygrads.py"
in "C:\Python25\Scripts", which is the same as clicking the shortcut
in windows start manu.</DIV>
<DIV> </DIV>
<DIV>3. How to use other IDEs such as IDLE and Pythonwin with
PyGrads?</DIV>
<DIV> </DIV>
<DIV>4. What's the relationship among Python, IPython, PyGrads and Grads?</DIV>
<DIV> </DIV>
<DIV>5. Could you advise a well-suited custom when using PyGrads? </DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
<DIV> </DIV>
<DIV>Peter Huang</DIV>

<DIV>Dear Pythonistas, </DIV>
<DIV><BR class=webkit-block-placeholder></DIV>
<DIV> I just uploaded a new version of PyGrADS to <A

<DIV><BR class=webkit-block-placeholder></DIV>

<DIV><BR class=webkit-block-placeholder></DIV>
<DIV> For the first time I am including a win32
installer as well as a win32 superpack for those of you who do
not have no Python whatsoever installed on your Windows box and
would like to give it a try. You can find more information in the
Wiki:</DIV>

<DIV><BR></DIV>
<DIV> This version cleans up some minor API issues and has a
more consistent naming of the main classes. It should be pretty much
backward compatible with v1.0.7, though.</DIV>
<DIV><BR class=webkit-block-placeholder></DIV>
<DIV> Be sure to run the <SPAN class=Apple-style-span
style="FONT-WEIGHT: bold">examples</SPAN> and check the plots:</DIV>

<DIV> We are still working on the Examples page in the Wiki.
Let me know if any of you would like to help with the
documentation.</DIV>

<DIV> <SPAN class=Apple-style-span
style="FONT-WEIGHT: bold">Grads v2 compatibility:</SPAN> like the
previous version, only the very basic <SPAN class=Apple-style-span
style="TEXT-DECORATION: underline">GaCore</SPAN> class works with GrADS
v2. (The test suite pytests first introduce in v1.9 has recently been
ported to v2; pytests only requires GaCore.) The ability of python to
exchange data with GrADS requires OpenGrADS extensions not yet available
in v2. </DIV>
<DIV><BR class=webkit-block-placeholder></DIV>
<DIV> <SPAN class=Apple-style-span
style="FONT-WEIGHT: bold">A call to volunteers</SPAN>. Here is a sample
of some of the features we would like to see implemented in
PyGrADS:</DIV>
<DIV>
<UL>
<LI>Better handling of satellite imagery, with seamless integration of
AREA, GeoTiff and some basic KML functionality
<LI>Integration of VTK or any other volumetric visualization python
package
<LI>Neural networks: integrate one of the many available NN python
modules so that network design and training could be accomplished
using simple and familiar GrADS expressions
<LI>Wavelet transforms, including some wavelet based compression
algorithms
<LI>Comprehensive set of statistical functions for analysis of climate
variability: better EOF capabilities, SVD, CCA, POP analysis, kernel
density estimates, time series analysis, etc
<LI>Some simple client/server implementation through XML-RPC or
equivalent protocol
<LI>Better Java integration through Jython: implement GaNum
functionality through JNumeric, 3D/volumetric visualization capability
through visAD, ...
<LI>Some GUI demonstrations using wxPython or any other python
toolkit. For example, a "GFS Workbench" tool that would bring together
GFS forecasts through OPeNDAP, observational data and satellite
imagery. </LI></UL>
<DIV>If you have some python experience in any of these areas and would
like to lead or get involved in any of these efforts (or anything else
that interests you) just drop me a note.</DIV></DIV>
