Analysis algorithm1) Images
Cy5 = Red Cy3 = Green

2) Grid Flexibility
Enforce grid constraints = yes
Local flexibility = 6.0 pixels
Flexibility = 75%

3) Quality Control
Empty spots = no
Poor spots = yes
Find negative spots = no

4) Measurements
Background buffer = 2.25
Background width = 5.0
Auto seqmentation = no
Signal low cutoff = 20%
Signal high cutoff = 100%
Background low cutoff = 0%
Background high cutoff = 88%

5) Poor Spot Parameters
Contamination of Background/Signal = no
Ignored pixels % = yes (setting = 69)
Open perimeter = no
Shape regularity = no
Area to perimeter = yes (setting = 0.6)
