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

Nick,

1) seems to be reasonable to me: Don't worry about the temporal discontinuities because the correlation computation only focuses on the relationship at the same time point (multiplication), but not across time points (only summation).

2) is fine, but would probably render similar results as 1).

The problem with 4) is that you could only remove the *average* condition effect (across trials) from the data, but not the variability across trials.
