[caret-users] Monkey atlases

Hi all,
I have two questions:

1 - Exactly where can I download the Macaque datasets? Specifically,  
I'm looking for the paint files for the various cytoarchtectonic  
parcellation schemes. I've tried to download the Macaque atlas specs,  
but all I get is the spec files, with no associated files. I have been  
able to download some of relevant paint files as part of some tutorial  
datasets, but I was wondering if there is one place where I can find  
all the relevant files.

2 - Ultimately, I am looking to convert the macaque cytoarchitectonic  
parcellations into volumes. Ideally, I would convert say, the F99  
scheme to one volume, with each region having a different 'intensity'  
value in the volume. Is there a simple way of doing this? The only way  
I could see was to use Region of interest operations, select nodes  
within a certain paint column, and convert them to a volume, but I had  
2 problems with this: (1) I could only figure out how to do it on a  
region-by-region basis, meaning that trying to extract all regions  
would take a long time; and (2) whenever I did try to create a volume,  
the file seemed to be dimensionless; i.e., I could select a volume in  
the 'model' button, but it appeared empty and I could not scroll  
through the slices. I was wondering what the easiest way of achieving  
this goal is, and where I am going wrong.

Perhaps the surface-based cytoarchitectinic parcellations were  
generated from volumetric data. If so, where could I download them?

Any help is much appreciated.
Thanks,
Alex
