@chinmay.chinara Sorry, I may not allowed to share it due to privacy reasons since it's clinic data. But I found another post that followed the official tutorial and got the same error here (Error trying to use AAL3), which might be helpful.
And here are some environment-related information:

@Raymundo.Cassani Thanks for your explanation. I still don't quite understand why some voxels fail to find a corresponding mapping, and whether this is a common issue.
Additionally, I would like to ask if the linear/non-linear normalization is solely influenced by the normalization operation in brainstorm? (Because this issue has never occurred with the previous ten or so subjects, where I used direct SPM register & reslice for co-registration. This is the first time I've tried using ct2mrireg for co-registration, so I'm not sure whether it's induced by my procedure or data or something else).
Finally, are there any other solutions besides switching to linear transformation?
Thank you again for your kind and quick reply!
