Hi,
I want to transform a mask (subcortical mask with 17 structures, integer values) to MNI space. I used 3dresample and 3dfractionize, but none of them results correctly. Noting that I am transforming from fine ro coarse resolution. When I use 3dresample and 3dfractionize and I see the result by AFI, the mask appear at top left corner with most parts disappeared. Is there any comment?
I used the following comand:
3dresample -master MNI -prefix mask_MNI -inset mask
3dfractionize -template MNI -input mask -prefix mask_MNI -preserve
3dfractionize -template MNI -input mask -prefix mask_MNI -vote
Best,
Siamak
