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 Chirag,

That the number of components varies per run does not really matter. You would not want to simply concatenate them, since that would force the terms that happen to go in the same column to have the same beta weight. They should probably be zero-padded across all runs, and passed using multiple -ortvec options to 3dDeconvolve.

One way to do this would be to loop over the runs using "1d_tool.py -pad_into_many_runs". See Examples 4a and 4b from the 1d_tool.py -help output.

Does that seem reasonable?
