Dear Sir/Madam,
Does Pre-Processed MR images (for exampe imageId:92646) need AC-PC alignment?
Thank you for your help in advance
Sincerely
Thank you for your question to the ADNI MRI Core.
There is not a AC-PC alignment done as part of the ADNI pre-processing stream. So yes, if you would like them aligned you would be required to perform that as an additional step.
Thank you
ADNI MRI
