Dear Katherine,
sorry to hear – two things:
1. please completely ignore the warning about the Image Calculator. It’s actually a “feature not a bug” we abuse the SPM Image Calculator to get images into the exact same space. It’s misleading for users, of course, and I wanted to disable the warnings for a long time already.. But in general you can safely ignore all warnings in Lead-DBS..
2. Regarding the error – it seems to happen in the “Show Normalization” Step (not in the actual normalization process). So I think images should have been normalized. You could check e.g. with SPM check coreg or 3D Slicer whether gl*.nii files are in MNI space (e.g. compare them to the file mni_hires.nii in the lead/templates/ folder).
It’s still very weird that you cannot visualize normalization directly in Lead-DBS.
To debug, could you please comment lines 22 and 126-128 in ea_show_normalization and rerun the “Check Normalization” Step only?
Post the error message here then if you get the chance.
Best, Andy
