dear fsl-experts,
i would like to use siena on a large number of subjects (all will be
scanned 2-3 times). after i have tried almost all options, the bet
brain extraction is still NOT ok around the eyeballs. a combination of
the [-f 0.3] and [-g -0.1] gets it close, but the extracted brain is still not
perfect, some of the eyeballs and brainstem is detected as brain.

is there a siena script there the [-g]-option is included?
or would you advise me to manually remove (i.e. paint out) the critical
areas (i.e. the eyeballs) in the original data?

thank you very much for your help!
best regards, isa.
