Spot Flag: spots are flagged if the PCR did not work (no band or a doublet), or if there was something abnormal about the hybridization.
CH1I: channel 1 intensity (Red probe)
CH1B: channel 1 background
CH1D: channel 1 difference
CH2I
CH2B
CH2D
CH2IN: data for channel 2 normalized to channel 1
CH2B
CH2D
CH1AB
CH2AB
SPIX: number of pixels in the spot
BGPIX: number of pixels around the spot used to calculate the background
RAT1: red/green
RAT2: green/red
RAT1N: red/normalized green
RAT2N
MRAT
REGR: Each spot is made of many pixels, and the red/green ratio is measured for every pixel. The data is graphed as a scatter plot with red signal along the Y axis and green signal along the X axis for every pixel. Ideally, every pixel would have the same color (r/g ratio) so that all of the pixels will line up along a straight line. The slope of the line indicates the r/g ratio. The regression ratio is a best fit line through all of the pixels in the red/green scatter plot.
CORR: regression correlation is a measure of how well the points on the scatter plot fits into a straight line. Numbers close to 1 mean good agreement between the individual pixels, numbers close to 0 means a wide variation in the color of each pixel.
