[pymvpa] within chunk permutation only for training set

[Richard Dinga]

Hello,
I was playing with a permutation schemes. There is one case I don't know
how to do

If I want to shuffle targets within chunks, I would use limit='chunks' in
my permutator,
If I want to shuffle targets only in test set, I would use
limit={'partitions': 1},

How can I shuffle targets within chunks, but only for the training set?

limit={'chunks':[0,1,2,3], 'partitions': 1} is not limiting shuffling
within chunks, and
limit=['chunks', {'partitions': 1}] doesn't work - RuntimeError: Unhandle
condition error (also my spellcheck is shouting, shouldn't it be unhandled
instead?)

Thanks,
Richard
