Unsupervised image segmentation for microarray spots with irregular contours and inner holes

BMC Bioinformatics

Table 1 The table exemplifies background corrected intensities, R, and G, in units of 1000 counts, the R/G ratio, the regression ration rR, and the coefficients of determination, R ², for two spots, i.e., for spots no. 100 and 3260 on microarray ID 20385 shown in Fig. 1

Spot		R/1000	G/1000	R/G	rR	R ²
Perfect	GenePix	46.56	37.84	1.23	0.71	0.87
	Our results	51.59	40.45	1.27	0.70	0.87
		(45.73)	(37.74)	(1.21)
Irregular	GenePix	28.63	17.68	1.61	1.41	0.76
	Our Results	65.53	37.532	1.74	1.18	0.76
		(19.29)	(11.59)	(1.66)
Pearson correlation		0.935	0.919			0.94

Values of GenePix are compared with our results. The last line gives the Pearson correlation between GenPix and our results for all spots of an experiment (ID 20385). In parentheses are the R and G values inside the ellipses
