Hi,

I have a tiny little feature request for 3dDeconvolve. I only mention it because it's probably one line of code in afni, vs. many lines and room for error if I take care of my problem otherwise, and it might be useful for others.

There is already the option of "stim_times_subtract," which is useful when for some reason you had a different number of discarded images at the beginning of a paradigm. I was wondering if you could add an option for "stim_times_scale" which would multiply all the times by a specified factor.

The reason is, I have a paradigm that does its timing by counting pulses from the scanner, set to 39 slices per TR, and I boneheadedly ran a subject with 40 slices instead, squeezed into the same TR (2 sec). So my stimuli ended up being presented slightly earlier than planned. To correct for this, I would multiply all my stimulus times by (39/40), or 0.975. The error does add up to several seconds by the end of a run. I could do this by modifying my stim_time files, but it sure would be cool to be able to just stick that one line in afni. Any chance?
Thanks as always!
