Wolf,
Please keep the list posted as to the findings from your work in this vein.
The amount of smoothing and loss of info necessary to rescale your images would seem to make the results suspect to me - especially when trying to take the activation maps back down to the 'animal model.'
I am very interested in what you find.
Best of luck.
Jason

Subject: [FSL] applying flirt transformation matrix after rescaling
Hi all,
If using flirt on animal brains it was in general suggested to rescale
the data and fake a human sized brain. If I obtain a transformation
matrix using this method, how di I nned to modify it to apply the
transformation on the original data? For example I rescale EPI and HiRes
Images with a factor of 3, perform flirt, which gives me a
transformation matrix. Now I would like to apply this transformation
matrix on an activation map, so what modification are required?
Thank you for all the help!
