Hi Mark,
Thank you very much for your reply, but I am already doing that for SMO and I have no problem,
But what you say does not work for SMOReg?
What do you suggest?

The input ARFF file that you use with SMO and the precomputed kernel
matrix needs to have two attributes - the first is an index for the
rows/columns of the matrix and the second is the class attribute. The
index attribute must be declared as nominal. We should probably allow
the index attribute to be numeric too, but this would require that the
user remembers to turn off normalization in SMO.
Cheers,
Mark.
