Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

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

Hi Rick,

I was trying the WAV and BLOCK options in 3dDeconvolve and ran this following command, assuming my stimulus is shown for 2 sec at the very beginning.

3dDeconvolve -nodata 15 2.5 -num_stimts 2 -polort -1 -local_times -x1D stdout: -stim_times 1 '1D: 0' 'WAV(2)' -stim_times 2 '1D: 0' 'BLOCK(2,1)' | 1dplot -one -stdin -xlabel Time -dx 2.5 -ynames WAV BLOCK

But somehow, the peak from WAV output seems to be delayed by a TR when compared to the output from BLOCK function. Why is this the case and then on what basis should we decide what to use?

Thanks,
Srikanth.
