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 Daniel,

Thank you for your reply.


Just to see that I understand you correctly..
You write: "an important point to remember is a half-voxel shift (the maximum interpolation) will introduce just as much interpolation as a seven and a half voxel shift, so you may not need to worry that much about differences between runs".

Does this mean that that after the 6 parameter (rotation/translation) rigid-body transformation, the maximal interpolation that can be introduced is 0.5 voxel in any case, independent of the initial distance in space between datasets? (I take your point regarding aligning the centers).

Best,
Uri
