P-value estimates for comparison between alignment columns and residue frequency vectors: random simulations show general consistency with null model. (A-C) For different emission vectors based on real alignment columns, large sets of random columns of three different sizes N were generated, and P-value estimates by PEAC (Pestim) were plotted against experimentally estimated P-values (P*, see text for details). Sets of emission frequencies are shown as bar graphs in inserts.
