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

That is not a good idea. Instead, cut each subject pair along the Z axis into multiple (e.g., 5) portions. Suppose you have 100 slices along the Z axis:

3dZcutup -prefix SubjectPair1A -keep 0 19 SubjectPair1+tlrc
3dZcutup -prefix SubjectPair1B -keep 20 19 SubjectPair1+tlrc
...
3dZcutup -prefix SubjectPair1E -keep 80 99 SubjectPair1+tlrc

Then run each of these 5 subsets with 3dISC separately. In the end, use 3dZcat to glue the results together.
