That means it could not find any CSF voxels. Try checking the registration. It could also be that this is a subject with really small ventricles.

Hi list,
During fcseed-sess -s subj -cfg vcsf.config
a subject produces the follow error.
I have rerun recon-all, cheched aparc+aseg with tkmedit. They seem to be ok.
Why this error is produced?
Thanks
Stefano
