One possibility is to use timing_tool.py with something like
timing_tool.py -timing **StimulusOnsetTime** -timing_to_1D *OutputFileName* -tr *YourTR* -stim_dur *StumulusDuration* -min_frac ... -run_len ...
Do the above for both your +1 and -1 parts with stimulus timing (not TR). Then you can do the rest (subtraction, waver, ...)
