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

Thanks Rick, that is interesting. So motion during the acquisition of the interleaved slices will cause this 'striping' artifact which is therefore not eliminated by applying slice timing correction?

Previously posted image was
to3d + 3dTshift + 3dvolreg
if I now omit the 3dTshift command, run
to3d + 3dvolreg
and perform the instacorr without manually changing the colorscale at the exact same coordinates as in the previous image you'll see the 'striping artifact is there too but looks slightly different (see screenshot attached). Not entirely sure what to conclude from this.
