Hi - you're right that the tissue priors (I assume you're using this
option otherwise the registration transformation wouldn't matter) are
in 2mm MNI space. However, the GUI says that you need to enter the
"Standard to Input" transform - hence it sounds like you need to
invert your transform.
Cheers.
