The empirical probability density of alignment and compositional P-values from shuffled sequences. 10 000 shuffled mouse query sequences were compared using S-BLAST to shuffled human RefSeq (20) sequences from Build 35 of the human genome. For each query, the alignment P-value Pa of the best match to the database was found, and the compositional P-value Pc was then calculated for the database sequence involved.
