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 Paul,

Can you verify whether the EPI times series datasets
have the proper timing in them? Use "3dinfo -VERB"
(upper case) to check the "Time-offsets per slice"
line.

It would be best to properly populated the dataset
to begin with. Otherwise, such timing would have to
be altered in 3dTshift via "-tpattern @TIMING_FILE",
which would have to be passed via -tshift_opts_ts,
and which would probably beg for use of -copy_files.

Of course, uber_subject.py does not have a direct
way to set such options, so they would need to go
into the afni_proc.py command. That would be much
easier to do when scripting afni_proc.py directly.

Going back to the beginning, can you verify whether
the original timing files have such information?
If not, maybe just try to add it first. Note that
3dTcat can be used for that, as well as to3d.
