Re: Convertion from nominal to numeric

> That doesn’t work either.

Works fine for me using the anneal UCI dataset.

Before:
@attribute family {'?',GB,GK,GS,TN,ZA,ZF,ZH,ZM,ZS}

Using the following filter setup:
weka.filters.unsupervised.attribute.RenameNominalValues -R 1 -N GB:11,GK:12

After:
@attribute family {'?',11,12,GS,TN,ZA,ZF,ZH,ZM,ZS}

Are there maybe spaces in your labels (leading/trailing) that could
make the matching fail?

Cheers, Peter
