External Email - Use Caution If you are referring to the T1 raw images, no they appear normal and the standard Freesurfer pipeline generates correct volumes.
If you are referring to the DTI raw images off the scanner, they also don't appear to have brain parts missing, although some appear more noisy and pixelated than others. This is a mTBI subject with no other anatomical brain anomalies scanned with a Siemens 3T. ------------------------------------------------ Re: [Freesurfer] Freesurfer 6.0 - Tracula - Segmentation fault Yendiki, Anastasia Wed, 19 Sep 2018 13:20:02 -0700 Do the raw images look like that too?

See attached screenshot. I did not use a configuration file, I simply accepted all defaults and kicked off the process with -s and -i flags. ------------------------------------------------ Re: [Freesurfer] Freesurfer 6.0 - Tracula - Segmentation fault Yendiki, Anastasia Wed, 19 Sep 2018 09:02:47 -0700 Hi Matt – It looks like some sort of registration issue. When you display the FA map (dmri/dtifit_FA) and structural segmentation in diffusion space (label/diff/aparc+aseg), do they look fine? Is there any part of the brain that is cut off from any of the images? Also, can you attach your config file? Thanks! a.y
