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 All,

This is a very basic question.

1. The AFNI22_Indiana PDF states that you can use AFNI to look across runs to look for habituation effects.
2. How is this done? Is there an example of how to do use? I am assuming this is a simple command in 3dDeconvolve?
2b. Would this then require creating separate stimulus timing files for each run and condition. For example:

Subj1_run1_faces
Subj1_run1_houses
subj1_run2_faces
subj1_run2_houses
....
....



Currently, we have 4 runs with 3 different conditions. Runs are concatenated and contrasts are analyzed on the group level. Stimulus timing files are one text file with columns referring to events and rows indicating runs.

Thanks!
