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 Yu,

It is hard to know the affect of the quatern and
qoffset values (why would the offsets differ? that
is strange). But it looks like the TR has changed
from 2.0 to 4.0 between them, as well as that
slice_duration, both of which are a bit strange.

You could see what either Dimon or dcm2niix_afni do
with the Dicom files, just for comparison. It would
be good to know what the correct values are.
