Subject: [Freesurfer] Easyreg > cortical parcels missing after SynthSeg with --parc option ?

        External Email - Use Caution       

Hello Freesurfer Developpers,

I attempted to run mri_easyreg (Freesurfer 7.4) between two MP2RAGE UNI
images (acquired on a SIEMENS PRISMA 3T).

First, I did not include segmentations, as I understood that EasyReg
would run it for me.

But it didn't. I don't know why.

Then I first ran mri_synthseg with the --parc option on the two images.

I checked the results, and saw cortical labels on both hemispheres.

But when I ran again mri-easyreg adding these images (--ref_seg
--flo_reg), I get again the > no cortical parcels.

What did I do wong?

Any hints?

Thanks in advance for your help.

Best,

Eric
