SEEG contacts' anatomical location

Thanks a lot! You are so efficient!
But in the process of trying, I found that although AAL and other atlas based on MNI coordinates are normal, there are many contacts marked as 'unknown' in some other atlas. In addition to the contacts that are outside the skull, there are some contacts that can display the region normally in the MRI viewer, are also marked as 'unknown', which means that the table and the MRI viewer have different results for the same location. What is the problem?
