Example of positive constraints used for syn-expression study [29]. For a set of genes, we estimate the correlation between the image intensities, and use the correlation matrix as positive constraints. High correlations (red entries in the constraint matrix) indicate expression co-location. use these to constraints the clustering o gene expression time-courses, for finding genes which are co-expressed
