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

Hello,

I created regressors to model when participants made a (1) correct response (2) incorrect response (3) did not respond at all. My regressors are structured as such: (stimulus onset): (duration).

I have time points for the "correct responses" and "incorrect responses" regressors, but sometimes I don't have any time points for the "did not respond at all" regressors. As a result, my 3dDeconvolve was not running. To alleviate this issue, I inserted "-1:1" for each of my runs in the regressor files without any timing values. With this, I specified "allzero_OK" and 'GOFORIT 10" in my afni_proc script. I just wanted to verify that this was the correct approach?

I also got several error/warnings messages in the 3dDeconvolve.err output as a result of above. I just wanted to make sure that these warnings were "okay" and due to the fact that I specified "-1:1" in my regressors with no actual timing information. Since I specified "GOFORIT 10", I want to make sure that 3dDeconvolve isn't bypassing other errors.

Thank you very much,
Tamara
