Error occurs when tring to use SMO -C for parameter tuning

[fracpete]

The option handling (inherited from Weka) can be sometimes a bit confusing. The "-W" option usually only takes a single argument, which is the scheme name. Options for that scheme have to be supplied after the "--" meta-option, which has to be placed at the end of the command. Your command would therefore look like this:
java -cp "C:\Users\xxx\scikit_ml_learn_data\meka\meka-release-1.9.2\lib*" meka.classifiers.multilabel.BR -W weka.classifiers.functions.SMO -t "C:\Users\xxx\AppData\Local\Temp\tmp8k72pc2i.arff" -T "C:\Users\xxx\AppData\Local\Temp\tmppka5mk9h.arff" -verbosity 5 -l "C:\Users\xxx\AppData\Local\Temp\tmpzp4xpsjt" -- -C 1.0

I'd recommend to use the Meka Explorer to configure your scheme, copy/paste the commandline (via right-click) and then just add the java call at the start and all other general options (datasets, verbosity, ...) right after the first classname.

Great! This solved my problem, thanks!
