AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Not directly; that is, there is no program for that purpose. You could approximate such a mask in several ways, but it would depend on how accurate you needed it and how much suffering/experimentation you were willing to undertake.

The most straightforward way might be to register the EPI to the TT_EPI+tlrc dataset with @auto_tlrc. Then use the Talairach atlas white matter mask, and back transform it to the +orig space (or operate entirely in +tlrc space). This would be crude, and not subject specific.

More elaborate methods could be devised, but I won't go on about them because my guess is that you want a pre-packaged solution, not a "try something like this and see what it looks like" suggestion.
