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 Michael,

I don't think that scaling the timing for regression analysis would generate the correlationship between what subjects perceived as pain and their real response during the experiment.

Instead I suggest that you go ahead and run 3dDeconvole with the original stimulus timing files (without scaling), and then at group level run regression analysis with the pain perceptual ratings, or run ANCOVA with the pain perceptual ratings as a covariate if you have other factor(s) to test. Let me know if I can be of any help in this regard.
