Hi,
I have bias-corrected and co-registered longitudinal images, and I'm
interested to use Freesurfer to construct unbiased within-subject templates
(to be used in SPM). Using mri_roubust_template, I get the following error
message on some (not all) of the subjects. I was wondering whether I could
use options/flags to avoid this.
--------------------------------------------------------
ERROR: All entries are zero! Images do not overlap (anymore?).
This can have several reasons (i.e. different modalities, different
intensity scales, large non-linearities, too diff. voxel sizes ...)
Maybe use --transform <init.lta> with an approx. alignment
obtained from tkregister or another registration program.
Or do some prior intensity correction?
--------------------------------------------------------
All the best,
Arman
