Hi,
I'm not sure by what you mean when you say "wrap my 2-D image" or
"project
a rectangular 2-D images ... onto the surface of a 3-D MRI brain image".
If the 2-D image corresponds to a cross section *through* the volume of
the 3-D image then this is fine. If, instead, it consists of values
corresponding
to "surface" voxels of the brain then it is not possible.
It should be possible with flirt to register your 2-D slice onto a 3-D
image
if you are in the first situation above. In this case all you need to
do is use
the 3-D image as the reference and the 2-D slice as the input, although
getting an initial orientation which is "close" is often critical in
these situations.
You can either use pointflirt or nudge to help you with this.
If this doesn't answer your question then please provide us with a
more detailed
description of your problem.
All the best,
Mark
