I would like to register the BCI_DNI Atlas to a T1 template (MNI152 non-linear asymmetrical version 2009c)
However, the pial surface extraction stops at some point and seems not to catch the right part of the brain (see screenshot)
PS: setting cost function to “least squares” or “standard deviation” does not solve the problem. With standard deviation it looks bit better, but still some remaining brain tissue (frontal cortex) outside of the mask….
