Lets return back to the mailing list ;) might be of interest to public

In general, classifier with RFE should behave as any other classifier...

See attached your exact code to use RFE-ed classifier (I've just changed
proportion to be removed to 50%, and enabling debugging output so
we could get some basic progress information from RFE).  It runs fine on
test datasets for binary and multiclass...  So the problem might be
indeed in dataset somehow?

What does

print PyDat.summary()

say?

What version of pymvpa do you use btw?

as for
>        raise UnknownStateError("Unknown yet value of %s" % (self.name))
>    mvpa.misc.exceptions.UnknownStateError: Exception: Unknown yet value of
>    feature_ids
to access them you should have enabled 'feature_ids' of your classifier,
not of the RFE per se (just as I've done in the attached script)

;)
