The default measurement order in the table is as follows:
* Field - Name of a field where the spot is located
* Metarow - Number of metarow in the metagrid where the spot is located
* Metacolumn - Number of metacolumn in the metagrid where the spot is located
* Row - Number of row in the subgrid where the spot is located
* Column - Number of column in the subgrid where the spot is located
* GeneID - Gene ID information for the spot
* Optional Probe Annotation Fields for the spot.
* Flag - Numeric code of the flag for the spot (0 - no flag, flag codes 1,...,7)
* Signal Mean - Pixel intensity averaged over the local signal region
* Background Mean - Pixel intensity averaged over the local background region
* Signal Median - Median pixel intensity computed over the local signal region
* Background Median - Median pixel intensity computed over the local background region
* Signal Mode - Mode pixel intensity computed over the local signal region (mode corresponds to the peak location in intensity distribution)
* Background Mode - Mode pixel intensity computed over the local background region
* Signal Area - Number of pixels in the local signal region
* Background Area - Number of pixels in the local background region
* Signal Total - Total pixel intensity summed over the local signal region
* Background Total - Total pixel intensity summed over the local background region
* Signal Stdev - Standard deviation of pixel intensities over the local signal region
* Background Stdev - Standard deviation of pixel intensities over the local background region
* Shape Regularity - First the signal area of a spot is inscribed into a circle. Then the number of non-signal pixels that fall within this circle is computed and divided by the circle's area. This ratio is subtracted from 1
* Ignored Area - Area of ignored regions directly neighboring ("touching") the signal area is computed
* Spot Area - Signal Area plus Ignored Area (pixels)
* Ignored Median - Median pixel intensity computed over the local ignored region
* Area To Perimeter - This quality measure defines spot's circularity. The area of a spot is divided by the square of spot perimeter and multiplied by pi4. As a result, this measure ranges from 0 (highly non-circular shape) to 1 (a perfect circle)
* Open Perimeter - Computes the proportion of signal perimeter that touches the border of rectangular snip around the spot
* XCoord - X coordinate (in pixels) of grid circle corresponding to the spot
* YCoord - Y coordinate (in pixels) of grid circle corresponding to the spot
* Diameter - Diameter (in pixels) of grid circle corresponding to the spot
* Position Offset - Offset (in pixels) of the center of the grid circle from the expected position in the grid
* Offset X - X offset (in pixels) of the center of the grid circle from the expected position in the grid
* Offset Y - Y offset (in pixels) of the center of the grid circle from the expected position in the grid
* Expected X - X coordinate of expected position of the circle in the grid. Expected position in the grid is computed fitting least square lines to circle centers in every row and column
* Expected Y - Y coordinate of expected position of the circle in the grid. Expected position in the grid is computed fitting least square lines to circle centers in every row and column
* CM-X - X coordinate of the center of the mass of spot's signal region
* CM-Y - Y coordinate of the center of the mass of spot's signal region
* CM Offset - Offset (in pixels) of the spot's center of the mass from the expected position in the grid
* CM Offset-X - X offset (in pixels) of the spot's center of the mass from the expected position in the grid
* CM Offset-Y - Y offset (in pixels) of the spot's center of the mass from the expected position in the grid
* Min Diam - Diameter of the circle inscribed into the spot's signal region
* Max Diam - Diameter of the circle inscribed into the spot's signal region
* Control - Name of a control type for current spot (See Settings Controls/Alerts panel)
* Failed Control - 0 if the control passed all tests, 1 if at least one of the tests failed
* Background contamination present - 0 if the spot passed background contamination test, 1 if it did not (see section 1.4)
* Signal contamination present - 0 if the spot passed signal contamination test, 1 if it did not (see section 1.4)
* Ignored % failed - 0 if the spot passed ignored percentage test, 1 if it did not (see section 1.4)
* Open perimeter failed - 0 if the spot open perimeter test, 1 if it did not (see section 1.4)
* Shape regularity failed - 0 if the spot passed shape regularity test, 1 if it did not (see section 1.4)
* Perim-to-area failed - 0 if the spot passed perimeter-to-area test, 1 if it did not (see section 1.4)
* Offset failed - 0 if the spot passed offset test, 1 if it did not (see section 1.4)
* Empty spot - 1 if the spot was qualified as empty, 0 if it was not (see section 1.4)
* Negative spot - 1 if the spot was qualified as negative, 0 if it was not (see section 1.4)
* Saturated spot - 1 if saturation was detected, 0 if no saturation was found for the spot (see section 1.4)
