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

Unlike 3dTagalign for affine alignment, 3dQwarp does not provide for tags in the alignment directly; however, you can be target particular locations. One way is to increase the weights at target points with the -weight option or the weight-enhancing options of -wball and -wmask. Besides that, you can also change the penalty factors with -penfac or -nopenalty to allow for bending in the warp.

Which Allen template are you using, and what is the use case here?
