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

Afni experts,

I am getting the following set of errors running afni proc.py on a subject:

*+ WARNING: Smallest FDR q [2 NE#0_Tstat] = 0.999899 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [4 NE#1_Tstat] = 0.999897 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [6 NE#2_Tstat] = 0.780828 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [8 NE#3_Tstat] = 0.358032 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [10 NE#4_Tstat] = 0.490714 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [12 NE#5_Tstat] = 0.999892 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [15 NN#0_Tstat] = 0.9999 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [17 NN#1_Tstat] = 0.999894 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [19 NN#2_Tstat] = 0.649399 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [23 NN#4_Tstat] = 0.999898 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [25 NN#5_Tstat] = 0.999899 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [28 RE#0_Tstat] = 0.999899 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [30 RE#1_Tstat] = 0.999898 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [32 RE#2_Tstat] = 0.871354 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [34 RE#3_Tstat] = 0.46837 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [36 RE#4_Tstat] = 0.744827 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [38 RE#5_Tstat] = 0.999898 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [39 RE_Fstat] = 0.299718 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [41 RN#0_Tstat] = 0.999898 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [43 RN#1_Tstat] = 0.999899 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [45 RN#2_Tstat] = 0.766395 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [69 RN_m_RE_GLT#0_Tstat] = 0.134647 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [70 RN_m_RE_GLT_Fstat] = 0.134647 ==> very few (if any) true detections

Intuitively, it seems like it wouldn't be completely unusual to not have a significant cluster of activation for some conditions on a single subject. However, this is my first subject on a new study, and going through outputs from subjects from a previous study, I am not seeing these errors, which makes me think maybe this could be indicative of a problem.

Are these errors something that should alert me that there may be a problem, or relatively normal?

Thank you!
