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

1) There is no program directly for the "replace some volumes with averages of their neighbors" program in AFNI. A script to do this with 3dcalc could be written, but some issues would have to be resolved:
* what to do when time points 13,14,15 all have to be replaced?
* what if time point 0 has to be replaced (there is no time point -1)?
* what is the form of input (a list of indexes or a 0/1 time series indicating keep/replace)?

2) If the 7 runs are so far apart that no individual sub-brick will work as a base (what is the symptom of the failure?), one approach is the one you mention. Another approach would be to use the -zpad and -twopass options -- these might make the registration work.
