Dear Freesurfers,

I'm have a question regarding the GEMS hippocampal segmentation. I saw on the wiki how to run -hippo_subfields, but how do I access the atlas itself? What file is it under.

Also, I'm not sure if I'm missing some files: whenever I try to do one of the individual commands using, for example, posterior_Right_Hippocampus.mgz, it gives the following error:

volumeInVoxels:

terminate called after throwing an instance of 'itk::ExceptionObject'

what(): itkMGHImageIO.cxx:216:

itk::ERROR: MGHImageIO(0x56b5c0): Can't find/open file: posterior_Right-Hippocampus.mgz

Abort trap

Also, upon searching through my freesurfer directory, I cannot find any posterior_Right-Hippocamus.mgz or posterior_Left-Hippocampus.mgz files.

Thanks very much for your time,

Raja
