asking about weighting misclassifications by type but rather

Do you mean you have a known weight for each instance that you want to
use? I don't think there is an easy way to set the weights of
individual instances -- you probably need to write a custom Loader
implementation that reads a data file that includes the instance
weights along with the attribute values.
