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

Adding a little more to this -

1. Cost function. Consider nmi in addition to the lpc and lpc+ZZ cost functions for differing tissue intensities like this.
2. Manual masking. Masking the data by hand with a simple sphere might be a good initial mask particularly if you have lots of other material, neck, shoulders,....
3. CT. If you happen to have a CT volume, you could compute a mask from that to remove all the gadgetry and align to the subject's T2 MRI. Then use the CT mask on the T2 dataset.
