INTENSITY FLOATThe foreground signal of this spot. Edit
BACKGROUND FLOATThe background signal for this spot. Edit
INTENSITY_SDEV FLOATStandard deviation of the foreground pixel intensity. Edit
BACKGROUND_SDEV FLOATStandard deviation of the background pixel intensity. Edit
X_LOCATION FLOATx coordinate of the spot centroid in pixels. Edit
Y_LOCATION FLOATy coordinate of the spot centroid in pixels. Edit
DIAMETER FLOATThe average diameter of this spot. This is useful to determine whether the spot is close to the expected size or is perhaps an artifact on the slide. Nominal diameter D is set in the Array Pattern dialog box. Edit
AREA FLOATThe area of the spot as the number of pixels used when calculating spot intensity. This is useful to determine whether the spot is close to the expected size or is an artifact, or has a satellite artifact on the slide. Artifacts that are connected to a spot can be recognized by a larger than expected area. The Nominal value of the area is pi*D^2/4, where D is the nominal diameter. Edit
FOOTPRINT FLOATThe distance between the expected position of a spot and its actual measured position. This is useful to determine the overall print quality of the microarray. This measurement also enables researchers to distinguish spots from artifacts on the slide. Edit
CIRCULARITY FLOATThe degree to which the spot matches a perfect circle. This is useful to determine the print quality of the microarray. Edit
SPOT_UNIFORMITY FLOATThe uniformity of the pixels used in the spot intensity calculation. This helps in determining the quality of the spot and aids in selecting the correct quantification output method (mean, median, total). A large uniformity value corresponds to a large distribution of pixels within the spot. In some cases, this may cause a mean or median value to fluctuate causing poor repeatability. A total quantification value may give a better choice in this case. Edit
BKG_UNIFORMITY FLOATThe uniformity of pixels used in the local background intensity calculation. This measurement can be used to determine the quality of microarray processes such as hybridizing and washing. More accurate spot intensities can be produced with a low intensity, uniform background around each spot. Edit
SN_RATIO FLOATThe ratio of the spot intensity to the standard deviation of the local background of all spots in the microarray. Spots with a low signal to noise ratio can be quickly identified for later review. Edit
