[pymvpa] Mac memory issues w/ large datasets

Hi all,

I'm having some trouble creating a dataset using a Nifti file that is  
approximately 1.6 GB in size on Mac OS 10.5 using python 2.5 and  
pymvpa 0.4.2.

Previously I had been importing using a mask which signifianctly  
reduced the size and so it was feasible, but it seems that Python's  
memory limits are keeping me from importing the dataset w/ no mask  
(since I want to do a searchlight).

I'm not sure whether a brain/non-brain mask has already been applied,  
but this seems like one possible solution.

Aside from that, has anyone faced this issue before?  Does anyone have  
a solution?
