I'm running 3dDeconvolve on 8 runs concatenated using the stim_times option, and I'm getting a warning like this for each of the stim_times inputs:

*+ WARNING: '-stim_times 10' file '/study/mrmri/fmri/pain/SP/processed/SP01/stim_times//fa_warm_pain.stimtime' has 4 duplicate and 12 near-duplicate times ???
++ Where 'near-duplicate' means within 51171062620f one TR

First of all, the "within" number seems a bit strange; all of them are approximately equal to that. There certainly seems to be something wrong with some calculation.

Here's the contents of the stim_times file associated with the specific error quoted above:
161.376
161.359
255.711
255.711
67.024
255.727
67.024
255.710

Obviously some of the numbers are duplicates of each other, but that shouldn't even remotely be a problem, because the times on each line are counted within that run, right?

Any enlightenment regarding why these warnings are appearing, and if something is going wrong internally to create the strange numbers? Thanks!
