I ran recon-all:

$ recon-all -sd /share/users/mfakhri/FS/subjects -subject 102109 -i T1w.nii.gz -all

Then I tried segmentation fornix and I used -f on the mri_cc command:

$ mri_cc -f -force -sdir /share/users/mfakhri/FS/subjects 102109

including fornix in segmentation

processing regardless of existence of cc in input volume
