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

You can use the '-nodata' option, as in '-nodata 300 1.0' where '300' is the number of time points and '1.0' is the time interval (in seconds) between them. After that, you set up the processing as normal, and the program outputs the analysis design matrix.

Here is an example copied from the 3dDeconvolve -help output
3dDeconvolve -nodata 300 1 -polort -1 -num_stimts 2   \
                            -stim_times 1 '1D: 10 150' 'MION(70)'    \
                            -stim_times 2 '1D: 10 150' 'BLOCK(70,1)' \
                            -x1D stdout: | 1dplot -stdin -one -thick
Here, the output is piped directly into 1dplot. If instead, you replace everything after '-x1D' with 'Xmat.1D', you'll get the resulting matrix (in this case, 2 columns) saved into a text file.
