scriptOp frame grab script

I’m trying to use scriptOp to grab a frame whenever a custom pulse is pressed (this will be automated eventually) but having some trouble integrating the code. I used the code from the snippet but it doesn’t seem to be quite right…any tips out there? I know i could use cache, but i need to keep saving images and create a long final image, so this seemed like the best first step. The code returns: File “/project1/script4_callbacks”, line 24, in onPulse
NameError: name ‘scriptOp’ is not defined

# called whenever custom pulse parameter is pushed
def onPulse(par):
	print('pulsed: ',par.name)
	if par.name == 'Frame':
		print('Frame Pulsed')

		inputTex = scriptOp.inputs[0]
		# copying the input texture into a numpy array
		nA = inputTex.numpyArray(delayed=True)
		# the first time numpyArray is called, None will be returned since
		# the delayed flag is set. This prevents a hang but also you need 
		# to take care of this manually.

		# output final texture
		scriptOp.copyNumpyArray(nA)

	return

The onPulse function is only given the parameter that was pulsed, unlike the onCook function. You can, however, access the owner of the parameter which will be the same node that the other functions receive as scriptOp.

scriptOp = par.owner
