Hi ,I'm a student who is new to labview and NI IMAX .I want to build an instrument that can measure activity of mouse (animal) by use the NI IMAX program ,grab pictures and subtract to get the pixel change. I look into this vi and try to run but there is an error at the histograph vi stated that "invalid image type"?

can anybody help explain this error?
Another question is that I want to plot curve between time and pixel intensity change and calculate the undercurve area to use as the indeicator of animal activity .How to convert the "image" to "pixel value" ? So that I can use this value to plot the curve between time and pixel change..
Thank you very much
