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

Hi Karel,

If you have text files of components that you want to apply in the final regression model, provide them using -regress_extra_stim_files, e.g., 

-regress_extra_stim_files resp.1D cardiac.1D
or
-regress_extra_stim_files regs_of_no_int_*.1D

To make these part of the baseline model (so that you do not get any betas for them, for example), use -regress_RONI to specify an index list of regressors of no interest (e.g. -regress_RONI 1 17 22).

Be careful with this though. Check the actual 3dDeconvolve command to be sure that the index list applied matches the regressors you supply.

If this gets too messy, I could probably add a more convenient option to pass many regressors of no interest in a single file, e.g. -regress_extra_orts MELODIC_ORTVEC.1D. Let me know if that would be more useful.

Does this seem reasonable?
