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

Thanks for the response.

Would concatenating the two runs of data be correct if the baseline conditions in each run were different?

I actually tried running a model wherein the tasks are concatenated- 3dDeconvolve in this case outputs colinearity warnings (becuase run 1 is highly correlated with the regressor for task 1 and run2 is highly correlated with the regressor for task2). I am unsure how this would effect the task beta estimates of activity.

Cheers,
Gerome
