Thanks - this did work. However, my functional data has a partial field of
view. When registering to standard space I used the three step approach
(func_image -> init struct image -> main struct image -> standard).
I hoped that a similar approach could be performed when registering to
single subject space. In other words to select an initial stuctural image
and replace the standard image by the high resolution structural scan. Feat
does not like this idea, since the initial structural image cannot be
selected if the main structural image is deselected. However, it seems like
a legitimate way to register the partial fov data to the high resolution
space. Is there a way to work around this problem?
Thanks,
Niels
