Hi Rick,

Yes, they do contain pre-SS volumes. I usually get rid of the first 10 or so TRs when I'm working with resting-state data, but I didn't want to remove too large of a chunk from the first block. However, I should probably remove 3-4 TRs instead of 2, as you say.

I've adjusted the stimulus timings, so that, e.g., if the first one is at 7 seconds, I subtract 4 seconds (=2 TRs) and end up with 3 seconds.

3dinfo -tr does return 2.0.

Ah, yes, I'm too used to resting-state pre-processing.. It seems like using a high-pass filter would be preferable!
