The redundancy of each library at different depths of sequencing. The x-axis is the number of sequence reads from each library. The y-axis indicates the number reads required to discover a sequence that does not cluster with the existing sequences for that library. Results after each round of sequence are shown for Br3 (squares) and Ret4 (diamonds). Other libraries are shown with circles. The point in the upper left is the non-normalized Ret3 library.
