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.
You may use either afni_proc.py or align_epi_anat.py. Motion parameters are saved, and only a single interpolation is applied to the epi data in the combined transformation that includes motion correction and alignment to anatomical data. Because the anatomical base data is from a separate session, you will likely need the "-giant_move" option for the alignment of epi to anatomical.
