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:

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

Doesn't 3dfim+ have a default polort value of 1? and there is default thresholding on, too, I think? From the program help:
[-polort pnum]     pnum = degree of polynomial corresponding to the    
                     baseline model  (pnum = 0, 1, etc.)               
                     (default: pnum = 1). Use -1 for no baseline model.
[-fim_thr p]       p = fim internal mask threshold value (0 <= p <= 1) 
                     to get rid of low intensity voxels.               
                     (default: p = 0.0999), set p = 0.0 for no masking.

3dfim+ wasn't really designed for this application, so I would check the default behavior...
