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, Experts,

I have a simple experiment. To illustrate, a trial begins with first a "fixation (+)" appears (500 ms), then the target stimuli 1(1000 ms), followed by the target stimuli 2(1000 ms). The trial ends with a jittered ISI (2000ms ~4000ms). I want to use two regressors for this in the 3dDeconvolve: regressor 1 for target 1, and regressor 2 for target 2. I remember that somewhere, people discussed that we have to consider the correlation between two events (i.e., stimuli 1, stimuli 2). If the correlation is low (i.e., nonsignificant), we then can separately estimate the two responses. How can I do the correlation analysis? I appreciate any suggestions.

Thanks so much,
Juan
