HI Elizabeth

that should definitely not happen. Something must have gone pretty dramatically wrong. If you upload the subject I'll take a look

cheers Bruce

Hi Eugenio,

It looks like the segmentation is missing all of the left hippocampus in the ASEG.

Is there a way to go in and manually correct this?

Best,

Elizabeth

  Dear Elizabeth,

  This is pretty unusual. Would you mind taking a look at
  aseg.mgz? Does the segmentation of the (whole)  left hippocampus
  look fine in ASEG?

  Cheers,

  Subject: [Freesurfer] Help with hippocampal subfield alignment

Hello FreeSurfer Developers,

I have run the hippocampal-subfields-T1 tag on a MP2RAGE scan for one of my subjects and find that the subfield segmentation for the left hemisphere only is off (pictures attached). No errors were reported in the log.

Is there a way to manually reset the alignment for only one hemisphere? Or is there a reason why it might be failing to segment that hemisphere?

Thank you,

Elizabeth
