Hi, Donna!
Many thanks for your explanation.
To be correct, the 'individual volume space' shall be 'group volume
space', I don't known if the expression is appropriate. In tbss, I register FA
of each monkey to the best target (selected by tbss_2_reg -n).
The format of my 2 sample T test result is *.nii.gz. With Flirt of FSL,
I have ever registered the result to 112RM-SL, which is also of the format of
*.nii.gz.
Now, I want to register the result to F99 volume. But caret seems to
have a very different file format, I don't know which fle set as reference in
registration.

You say individual volume space. Does this mean the data is for a single
monkey? I guess I'm used to thinking two sample t-test is for two groups, but
I guess not necessarily.

You must use something like FSL's flirt or fnirt to register your individual's
anatomical scan (T1 or T2) to the F99 anatomical scan. I assume your two
sample t-test results are already in the same space as the T1 or T2. If so,
then apply that warp to your two sample t-test results.
Doing this will let you view your test results overlaid on F99, but it won't
say anything about significance. FSL's randomise should have said something
about this when you ran the two sample t-test. You can view these results in
fslview, too.

You need a tool that does volumetric registration (e.g., FSL's flirt or fnirt).
There are many others out there as well.
