Dear Rick,

I'm coincidentally having a similar issue this afternoon. I've been running 3dDeconvolve on a dataset and received numerous warnings, such as:

*+ WARNING: Smallest FDR q [3 self#0_Tstat] = 0.999789 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [4 self_R^2] = 0.993538 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [6 other#0_Tstat] = 0.65011 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [7 other_R^2] = 0.648387 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [9 novel#0_Tstat] = 0.102798 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [10 novel_R^2] = 0.102293 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [12 all_stim_GLT#0_Tstat] = 0.604113 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [13 all_stim_GLT_R^2] = 0.601881 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [15 self-other_GLT#0_Tstat] = 0.579272 ==> very few (if any) true detections
*+ WARNING: Smallest FDR q [16 self-other_GLT_R^2] = 0.576629 ==> very few (if any) true detections

I highly doubt my data are that bad! :) I've been troubleshooting for a while, but to no avail. Would you mind looking at my command, etc.? Command is below; stim files (1 per condition) were each 1D files of 0s and 1s (I'm having trouble attaching them, so I'll email them to you).

Thank you very much for your time!

Cheers,
Jeff

The input file is a concatenated dataset of about 14 runs. Please let me know if you need any other information from me!
