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

Hi Bob,
Thanks! That is a very interesting idea. I read their protocol a bit but did not realize they were doing in this way. I agree with you that the field map result is semi-reasonable. For some parts it seems to make the EPI match structure better, but for some other parts it can over compensate (if I am not doing things wrong) and the performance seems to vary with subjects.

I will give a try for my future scans. So if my scan is A>>P phase encoding direction, should I just add a few TRs of scan with P>>A phase encoding direction?
