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

I thought it was worth clarifying, the data set is a few non-sequential 2D images. So felt 2D registration was more appropriate than using 3dvolreg. I referenced the discussion below to guide my choice to start this problem but the registration hasn't come out well at all. I've tried a few iterations tampering with the default values in 3dAllineate, but to no avail. My hope/thought is figuring how to source a ROI/mask of voxels in base to register ought to give the best result. I also tried -emask option using an inverted mask but was also worse. Any guidance with this is very much appreciated.
