Reply To: What is the meaning of each image filename?

Hi Hao,

No, ‘glpostop_ct.nii’ is calculated based on ‘rpostop_ct.nii’. It’s a two-step normalization: ‘postop_ct.nii’ -> ‘rpostop_ct.nii’ (aligned with anat_t1.nii) -> ‘glpostop_ct.nii’ (nomalized to MNI space). Since it’s the normalization of ‘postop_ct.nii’ in the end, I think it make sense to use ‘glpostop_ct.nii’. See in your preference file (Lead-dbs menu -> Preferences -> Edit Preferences File). ‘prefs.ctnii_coregistered’ and ‘prefs.gctnii’ are defined there.

Best,
Ningfei
