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.
Yes, that is right. With 4 separate conditions/regressors, you can then evaluate how linear they are, separate from the assumption of it in the AM regression. That would yield 4 betas in separate volumes. With only 4 though, it will be difficult to say anything strongly. But a scatter plot across entire ROIs might make it more clear.
