Dear Zenas,
We use a home made template for normalisations in animal fMRI using SPM. At
present it is derived from a single subject (similar to the Talairach
template) but we hope to create a more representative template from a
co-registered group of subjects positioned stereotaxically.
Creating a template is quite simple but here's a few tips which should make
it go more smoothly:
- use the 'header edit' function in SPM to scale your animal brains by 10.
This enable you to display the images in SPM at a sensible size, also you'll
be able to see the activation blobs when they are projected onto the glass
brain.
- use a sensible central anatomical reference to set as 'origin' for the
template and images to normalise. Again 'header edit' will do this.
- when normalising, you'll need to set-up custom bounding boxes and pixel
sizes.
I hope that is of use, any problems please let me know,
Andrew Lowe

Subject: About the normalization templates
Greeting,
I wonder that is it possible to do spatial normalization in animal
fMRI model.
Can I construct an animal templates and change part of the MATLAB source
codes
to achieve it?
Warmest Regards
Zenas
