[pymvpa] DecMeg2014 data analysis competition

[Yaroslav Halchenko]

Hi Emanuele,

Few questions:

1.  "The goal of this competition is to predict the category of a visual
stimulus presented to a subject from the concurrent brain activity."

to a NEW (unseen) subject or a subject among those present in training
set?

2.  what is the license on the dataset?  could it be
redistributed/acquired without signing in with g+/whatever?

Cheers!
