[Pebl-list] Finger Tapping Task

[Erik C. <e.c...@sm...>]

I am attempting to write a simple finger tapping task in PEBL.

My stimuli are 6 WAV files of beeps at various intervals:
subbeep1 <- LoadSound("sounds/subbeep1.wav") ## 250ms interval, 5s
subbeep2 <- LoadSound("sounds/subbeep2.wav") ## 290ms interval, 5s
subbeep3 <- LoadSound("sounds/subbeep3.wav") ## 330ms interval, 5s
supbeep1 <- LoadSound("sounds/supbeep1.wav") ## 1400ms interval, 15s
supbeep2 <- LoadSound("sounds/supbeep2.wav") ## 1800ms interval, 15s
supbeep3 <- LoadSound("sounds/supbeep3.wav") ## 2000ms interval, 15s

I have shuffled them to give me a random order which I want to present
to my participants like so:

stim <- Shuffle(subbeep1,subbeep2,subbeep3,supbeep1,supbeep2,supbeep3)

loop(s,stim)
 {
	## Trial stuff goes here - not worked out just yet...
 }

My problems is - how do I write out to my data file which of the stimuli
is being used? I can't do a Print(s) because the contents of the
variable is audio not a string.
