Hi Darren & others ...
I posted another solution to this issue on here a while ago:
I created an AFNI version of the avg152 standard which ignores the normal afni
coordinate conventions but instead uses the FSL standard brain conventions.
Then, I marked the acpc and tlrc markers on this brain. By putting this
brain (or a link) in any directory that has analyze files registered to the
avg152 brain, I can now just click on the 'tlrc' button and view the analyze
files in tlrc space, or at least something close.
Go to
ftp://geon.usc.edu/avg152T1_ana/
to download the files.

But, I really think this would be a good thing to coordinate between
AFNI and FSL
