Correlation coefficients between hybridisation patterns obtained with all 95,000 probes. Spearman's rank correlation coefficients (top right) and difference between mean of replicate pair-wise correlations of one isolate to mean of non replicate pair-wise correlations of other isolate, both reciprocal values are indicated below each other (down left). Reproducibility is demonstrated through the observed correlation values which are higher between the replicates than with samples from other species for most of the cases. Values from the same genera are highlighted in light grey and replicates from the same strains with a darker grey. Correlation can be higher between samples from different strain or species (indicated in italics) than between replicates, revealing the need of sorting out aspecific probes. P. aggl stands for P. agglomerans, P.vag for P. vagans, P. stew for P. stewartii subsp. indologenes, S. Typh for Salmonella Typhimurium, X.arbju for X. arboricola pv. juglandis, X.arbpr for X. arboricola pv. pruni, X.camca for X. campestris pv. campestris and X.tratr for X. translucens pv. translucens. Replicates are indicated from a to d.
