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

It might be good to use the -stim_times format for when the
stimuli occur, and to use BLOCK(T) for the basis functions,
where T is the duration of the given stimulus type.`

See Bob's notes from 2004 for details on using BLOCK():

[afni.nimh.nih.gov]
[afni.nimh.nih.gov]

Note that unless all stimulus types have durations over 15
seconds, you will not want to specify a 'p' term for the
magnitude (peak) of each regressor in BLOCK(d,p). Just use
the BLOCK(d) format.
