'waver -GAM -dt 3.0 -numout 684 -input RSF.stim.${iter}.1.1D' would work, but, since some of the stimuli are not TR-locked, I wonder the '-tstim' option in waver might better serve your purpose by running the following:

waver -GAM -dt 3.0 -numout 684 -tstim `cat RSF.stim.${iter}.txt` > RSF.resp.${iter}.1D

where RSF.stim.${iter}.txt is a column of the timepoints in terms of seconds (in stead of 0's and 1's as in RSF.stim.${iter}.1.1D) at which the stimulus is given.
