[pymvpa] Commonspace

[andrea bertana]

Dear all,

We are performing a few tests on hyperalignment, and we would want to
project a new participant's brain to a commmon space computed over other
participants' responses (all participants performed the same task).

However, in terms of scripting, it is not clear to us where the common
space is stored. We would need it in order to compute the transformation
matrix directly from our participant brain to the common space (same as
step 3 of hyperalignment).

We are mainly referring to the example described in this webpage -
http://dev.pymvpa.org/examples/hyperalignment.html

What we thought about was to get the 'commonspace' parameter from hyper
object (which seems to carry it as general one), and then evaluate
algebrically the transformation matrix from the new participant to the
common - space.

Are we missing something?

Thanks,

Andrea
