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

Well, I could look through the code and try to figure it out -- I don't recall the answer offhand, even though I wrote the code. But the easier solution is to try it and see. So here's a command 
3dDeconvolve -nodata 200 1.0 -polort 0 -num_stimts 1 -stim_times_IM 1 '1D: 20 80 140' 'SPMG2(18)'
1dplot nodata.xmat.1D
And the result of the plot (hopefully attached) clearly shows that the order is
  1. Polorts
  2. First stim time (20 s) first basis func ('raw')
  3. First stim time, 2nd basis (temporal derivative)
  4. Second stim time (80s), first basis function
  5. et cetera
The attribute for these columns is given in nodata.xmat.1D as 
ColumnLabels = "Run#1Pol#0 ; Stim#1#0 ; Stim#1#1 ; Stim#1#2 ; Stim#1#3 ; Stim#1#4 ; Stim#1#5"
