I am trying to collect the value of a specific cell in a jit.matrix. when i use the "getcell" attribute it gives me the values of all four channels (argb)... all i want is one value between 1 and 256. is there a simple way to output this value to a number box?

If by "one value" you mean the luminance of the cell, you will need to 

pass through jit.rgb2luma, to convert your matrix into a 1 plane. 

Otherwise, you could always just choose an arbitrary plane to track.
