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 Julien,

Ziad is out this week, just so you know. He may have something
additional to say as it's his program.

Most AFNI programs can handle "single time series" datasets.
Set the AFNI_1D_TIME environment variable to YES, and provide
your input in that form:

setenv AFNI_1D_TIME YES
3ddelay -input A.1D -ideal_file B.1D -fs 0.5 -T 0 -prefix del_A.1D

So dataset B.1D can be a single time series.

---

When deciding which is delayed, you might consider applying
the delay with the larger correlation term. If you input
those via -c and -d, you could use 'a*step(c-d)+b*step(d-c)',
where -a and -b are the delay values (in 1deval or 3dcalc).
