[pymvpa] Connecitvity Hyperalignment and SeedQuerryEngine

[Vincent Taschereau-Dumouchel]

Hi everyone,

First of, thanks a lot for sharing the connectivity hyperalignment code. You guys are doing awesome work.
I am starting to play around with it and was wondering about 2 things:

- Do you have an example of the arguments that needs to be provided? One of them is the SeedQueryEngine. I went through the code a little and I am having a hard time determining what this is exactly. 

- Also, can we use it not with surfaces but with typical volume data? I understand the problems associated with running a searchlight on volume data but I was just trying to take a quick peak at the function before processing surfaces and all.

Best,

Vincent
