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

Only indirectly. You could extract the column with 1dcat, save it to a separate file, then use that file for -stim_times,
as in

1dcat q.1D'[3]' > q3.1D
3dDeconvolve ... -stim_times 1 q3.1D 'BLOCK(5)' ...

You could also try this for the filename after -stim_times:

`1deval -1D: -a q.1D'[3]' -expr a`

where I've used the shell backquote operator and the '-1D:' feature of program 1deval to capture the desired data onto the command line. I don't actually know if this tricky approach would work with 3dDeconvolve, but you can give it a shot and see what happens.

However! Note that the various 1d programs all operate on rectangular files -- only 3dDeconvolve (and 1dMarry) deal with ragged files, where the number of values in each row is allowed to vary. If your 'q.1D' file is ragged, then neither of the above approaches works.
