Dear all,
i'm trying to map my fMRI data (from SPM2) on PALS-B12 surface.
I map volume-to-surface using 'MAP to SPEC FILE WITH ATLAS',
my option are:
1)PALS_B12.RIGHT_SumsDB-HomePage_SURF-ONLY.73730 (the spec file)
2)SPM2 (the ATLAS)
3)PALSB12 MultiFid map (73730,SPM2 space).
Then I trying to use 2 different algorithms:
1)AVERAGE VOXEL (with neigh.=0)
2)ENCLOSING VOXEL
If i understood well the 2 methods have to be quite similar
But the projecton on the PALS flat maps results quite different.
There is some one can explain me why?
Am I doing something wrong?
More , when i try to project the data from a meta-analysis, the results
are again different using the 2 algorithms. The projection on PALS FLAT
MAP obtained with AVERAGE VOXEL seems to be more precise, while the
projection of original FOCI of meta-analysis are clearly within this map.
Thank's much for the help.
