External Email - Use Caution Dear Haley,
The Matlab version of SynthSeg writes nifty files. You could run the FreeSurfer command to convert to mgz (and rename to aseg, along the way): mri_convert synthseg.nii.gz aseg.mgz Now: I don’t know if it’s possible to simply replace FreeSurfer’s aseg.mgz by this new aseg.mgz and keep running from there. I’ll defer to Doug and Bruce (CCed) on that.

You probably want to read in the existing aseg to get the header, then replace the data with the segmentation you want and then write it out Cheers Bruce -----Original Message----- From: freesurfer-boun...@nmr.mgh.harvard.edu <freesurfer-boun...@nmr.mgh.harvard.edu> On Behalf Of Haley O Higginbotham Sent: Friday, August 25, 2023 11:06 PM To: freesurfer@nmr.mgh.harvard.edu Subject: [Freesurfer] Import Matlab SynthSeg labels to FS External Email - Use Caution Hi, I experienced issues with segmentation (exclusion of large portion of cerebellum) and so used SynthSeg in Matlab (as the built-in mri_synthseg in freesurfer wasn’t working on my computer) to create the segmentation. Does anyone know how to import the resultant 3D categorical array containing the labels back into freesurfer (for the sake of further manipulating it in freeview and replacing the aseg file)?
