running an existing script
Hi, I'm trying to put together a lot of pieces of source code in matlab, java, perl and python. Im an expert when it comes to matlab, but novice in all the others listed above. However, I have integrated the java and perl code so they can be called from matlab. I know that there is a toolbox out there called Pymat but i think that uses 32bit activex so rules my configuration out. However I think I can hack in to the python command prompt from matlab. Basically I just want to run a single script from the python command window. Once I know how to do that I can be off on my way to perform the matlab interfacing. there is an example of the command I need in the python prompt at http://jboost.sourceforge.net/doc.html#cv . however, I can't seem to run the python script by typing the command on that link in the python prompt. Can I please ask how to set the current duirectory in python? the script I want to run is in a different directory to the one python is installed to -- http://mail.python.org/mailman/listinfo/python-list

Thanks to both of you for your help.
It's getting late here, I'll give it another try tomorrow

I've added the python directories to the environment variable "path"
in my computer (http://showmedo.com/videotutorials/video?
name=96&fromSeriesID=96), which means I can now call python from
the windows DOS-style command prompt.
My formatting must be wrong when calling the nfold.py script to run.
My connad prompt call and the computer's response look like this:
C:\Users\Adam\Desktop\JBOOST\jboost-2.2\jboost-2.2\scripts>nfold.py
nfold.py
File "C:\Users\Adam\Desktop\JBOOST\jboost-2.2\jboost-2.2\scripts
\nfold.py", line 13
print 'Usage: nfold.py <--booster=boosttype> <--folds=number> [--
generate | --dir=dir] [--data=file --spec=file] [--rounds=number --
tree=treetype]'
^
SyntaxError: invalid syntax
What I dont understand is that some of the parameters in the syntax it
printed back are in <> brackets, and others in [] brackets.
I assume this is something a regular python user could notice straight
away.
Please let me know, I'd be very grateful

I just tried
nfold.py --booster=Adaboost --folds=5 --data=spambase.data --
spec=spambase.spec --rounds=500 --tree=ADD_ALL --generate --dir=C:
\Users\Adam\Desktop\cvdata
in the dos-style command prompt. It didn'g vive a syntax error this
time, it just repeated my command back to me in text. I assume I
called code correctly, but it didn't make a new folder full of data
like it should have.

jboost 2.2, python 2.7
somehow I've just managed to delete all of the code in nfold.py, now
downloading it again...

Thanks a lot, must be getting close now...
I changed the indentation one lines 136-168, and put in the command
window:
nfold.py --booster=Adaboost --folds=5 --data=spambase.data --
spec=spambase.spec --rounds=500 --tree=ADD_ALL --generate
no syntax errors this time, it just said:
nfold.py: Your CLASSPATH is not set. You must place jboost.jar in your
CLASSPATH.
is that the chdir() command in python? and can I somehow set that in
the dos command window?
