Hi Rahul
That may just be an inevitable part of cross-subject anatomical variability. You could try explicitly registering them, or transform them all into Talairach coordinates which should help reduce the variability
(e.g. mri_convert -at $SUBJECTS_DIR/$subject/mri/transforms/talairach.xm <input volume> <output volume>
Cheers
Bruce

External Email - Use Caution
Dataset is taken from ADNI for Alzheimer's Disease Diagnosis.
Subjects are different. We want to extract slice between an exact range for all scans but when we are extracting we are facing issue, for ex. I want 80th slice in sagittal view to be extracted
but for some images they are similar but for most of the images the extracted slice is different.
