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

3dTshift infers the slice direction from the z direction (k dimension) of the storage orientation. With the exception of the voxshift option, these z slices are used for the relative timing offsets with the various timing patterns like alt+z, alt-z, seq+z, .... You can find the dataset orientation with "3dinfo -orient mydset". The last dimension of the 3-letter code determines the slice direction and order (top to bottom vs bottom to top, left to right vs right to left). So an orientation of RAI implies Inferior to superior axial slices. An orientation of PIR implies left to right sagittal slices.
