Thanks again Ethan, It did begin to run nfold.py this time, after I
added the environment variable "CLASSPATH" to my system. It threw back
a java error, but I guess this isn;t the right place to be asking
about that

Looking at the batch file I see a line that modifies the CLASSPATH, so try this before you run nfold.py (cut across two lines, but it's really just one): set CLASSPATH= %CLASSPATH%;../dist/jboost.jar;../lib/jfreechart-1.0.10.jar;../lib/jcommon-1.0.8.jar


Good luck!
