I used the Freesurfer7.1.0 version for the hippocampus subfield segmentation, and I use a coronal T2 scan as an additional to do the  segmentation

.

I'm wondering that the reason for the two black blocks in the sagittal and axial view is because I only use the coronal T2 anat scan for the additional scan? 

Can I add another axial scan for the T2 subfield segmentation without deleting anything (like hippocampal-subfields-T2.T2.log)? Thanks

Best,
