Re: [Freesurfer] aseg.mgz file not generated after recon-all

That flag is to perform only the subcortical segmentation, but there are are steps leading up to it that need to be done. If all you want is a subcortical seg, then you can just run mri_synthseg --i orig.mgz --o synthseg.mgz

External Email - Use Caution

Dear all,

I ran FS *recon-all -subcortseg -sd -subjid *and it was completed without any errors. However, when looking into the mri folder, there is no aseg.mgz file, only aseg.auto.mgz. Could you please explain why this is and how to get the aseg.mgz file?

Thank you.

Best wishes, Sara
