  1. The z scores represent mean cophenetic distances between all pairs of conditions with the same label, normalized by the distribution of mean distances obtained after randomly reshuffling condition labels. The overall z score tests for significant clustering within a given variable, and the individual z score tests for significant clustering within a given condition. Significant clustering (defined as |z| > 2) is indicated with a *The z-scores of individual batches are provided in Supplementary Tables S6 and S7.
