[pymvpa] Searchlight debug issue

[Geethmala]

Hi,
I still have one more doubt. Why does split[1] show only 5 chunks as opposed
to 6?
Isn't split[1] the training set?

-> result = transerror(split[1], split[0])
(Pdb)
>
/usr/lib/python2.5/site-packages/mvpa/algorithms/cvtranserror.py(176)_call()
-> if clf_hastestdataset and expose_testdataset:
(Pdb) print split[1]
Dataset / float32 825 x 2 uniq: 5 chunks 2 labels
(Pdb) print split[0]
Dataset / float32 326 x 2 uniq: 2 chunks 2 labels

Thanks,
Geethmala
