[pymvpa] full example fMRI dataset?

On your website here, http://www.pymvpa.org/examples.html#exampledata

there is the following text: "The dataset used in the /examples/ 
<http://www.pymvpa.org/examples.html#chap-examples> shipped with PyMVPA 
is actually a minimal version (posterior half of a single brain slice) 
of this full dataset. After appropriately adjusting the path, it is 
possible to run several of the examples on this full dataset."

I see the minimal version as the file bold.nii.gz - when I open a volume 
in this file, it is a single slice of the posterior half of the brain. 
Is it possible to get the "full dataset" that I think you're referring 
to (or maybe I just misread the description)? That is, I would expect to 
see the same file with 1452 volumes in it, but this time in each volume 
there are multiple, full-brain slices.

I had an earlier question to the newsgroup where the data I am trying to 
get working with the SMLR classifier is in the same format - each volume 
is multiple slices of the whole  brain, but I can't seem to get the 
confusion matrix to produce anything meaningful.

Thanks so much!
