Dear Yann, difficult to say without seeing the data. Because the main difference in version 12.5 is the handling of WMHs you can try the disable the option for WMH detection. However, this also depends on your data. If there are WMHs indeed present in your data it’s a choice between trying to fill WMHs for spatial registration (and a potential fail of that correction) and the affected spatial registration due to remaining WMHs in your data.
