Hi,
To do some higher level analyses in standard space and some in native
space you will need to run two different sets of higher level analyses.
Firstly, for the standard space:
Run all first level registrations to the avg152T1_brain and then
all higher level analyses as normal, first across sessions and then across
subjects/groups
Secondly, for the native space:
Re-run the first level registrations using the high-resolution structural
as the "Standard space" image. You can leave the "main structural image"
blank in this case (unselect the box). Then proceed onto the higher
level
analysis across sessions. The trick is to make sure that the
"standard" image
is the one corresponding to the space you want the results in.
This should be all you need to do.
All the best,
Mark
