I am analyzing some data from a site that acquires images that include a lot of neck tissue. I have tried BET using the -R option. This works well for some subjects' data, but for others, even with significant neck tissue still present (with a particular -f), a large portion of frontal lobe is cut off. Is there a good way to deal with this issue? Perhaps removing neck tissue first? Any ideas for how to do that if you think it will help?
Thank you.
