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

Nickolas,

The warning message indicates that 4 columns in the design matrix are all 0s. Add option -x1D in your 3dDeconvolve script, and spill out the design matrix. Then use tools such as 1dplot, ExamineXmat and xmat_tool.py to figure out what those zero columns correspond to in your stimulus timing file Listen.1D.
