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

Do you mean 3dTstat instead of 3dTcalc?

If you just want to get the average in a time series with 3dTstat without considering those outliers, you can use the sub-brick selector to specify the time range, such as

'File+orig[0..20][22..100]' (removing time point 21)

Sounds reasonable.
