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

The paper describing the algorithm used for EPI-to-structural registration in 3dAllineate has now been published:

ZS Saad, DR Glen, G Chen, MS Beauchamp, R Desai, and RW Cox.
A new method for improving functional-to-structural MRI alignment using local Pearson correlation. NeuroImage, 44: 839-848, 2009.
[dx.doi.org]

For your reading pleasure, a copy can be found on our server at

Movie rights have been sold, and George Clooney will appear in the role of Ziad Saad.

Also, I recently made a minor addition to 3dAllineate to implement a new '-final' interpolation method: 'wsinc5' which is a 10x10x10 weighted (tapered) sinc interpolation scheme. This method is highly accurate and should preserve edge features and time series variances well, but is also several times slower than the next most accurate method in the software ('quintic', which uses a 6x6x6 interpolation stencil).
