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 -glueto approach could be simplified up a bit...

If one of your 3d+time datasets is 710 TRs long, then
it would be enough to do: 

3dcalc -a dset.710+tlrc -expr 0 -prefix zero.710

If not, presumably 4blocks_zeros_ones_for_convolution.1D
is still 710 TRs. long. In that case it would be enough to
take a single volume and that 710 TR 1D time series as
inputs, and still output zeros: 

3dcalc -a mean_iso_HRF+orig"[0]"                \
       -b 4blocks_zeros_ones_for_convolution.1D \
       -expr 0 -prefix zero.710
