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,

Would you provide more detail on what you want?

For example, if the problem is that the mean is zero, it would be simple to pre-compute the mean (3dTstat -mean) and add it back in later (3dcalc -a TIME_SERIES -b mean -expr a+b). However, that should not have any effect on computations of functional activation.

So exactly how do you plan to compute the functional activation for the ROIs after 3dTproject? Neither correlations nor regressions should be affected by the zero-mean data.
