"SS" means "single-subject", while "ss" means "skull stripped".<br><br>Sorry for the confusing nomenclature.<br>If your data is skull stripped, you should use "ss" atlas.<br>
Usually linear transformation works between non-skull stripped data. However, sometimes some extra signal such as sinus interferes with the registration. In this case, you may need to do registration between skull-stripped images.<br>
For LDDMM, it is safe to use skull-stripped images.<br><br><div class="gmail_quote">On Tue, Jul 20, 2010 at 5:44 PM, Josselin <span dir="ltr"><<a href="mailto:j.houenou@yahoo.fr">j.houenou@yahoo.fr</a>></span> wrote:<br>

In many files provided, some have the letters "_ss" attached to them. What does it mean ? e.g. what's the difference between JHU_MNI_SS_FA and JHU_MNI_SS_FA_ss ?<br>
thanks,<br>
