ABOUT THE COVER
The cover image shows a Pearson correlation matrix of 51 anti-cancer agents analyzed in the Oncolines and NCI-60 cancer cell line panels (blue: high correlation, orange: negative correlation). The left triangle shows clusters and correlations using data from the Oncolines panel. The right triangle is identical to the left one, only based on NCI-60 data. Both data sets reveal similar clusters (some classes are indicated).
