Performance of BandLeader in multiplet identification: 3431 multiplets were extracted from 322 “finished” human and mouse BAC sequences. Plotted on the x-axis is the number of fragments per multiplet detected by sequence analysis. Plotted on the y-axis is the number of correct bands per multiplet identified by BandLeader. Numbers under the individual data points indicate the number of multiplets detected in the sequences for a given number of bands in the multiplet. For example, there was a single 11-plet identified in the sequences, and BandLeader identified correctly all 11 bands in the 11-plet. In another example, there were two 8-plets identified in the sequences, and all of the bands in all these multiplets were correctly identified by BandLeader. The inset summarizes BandLeader performance for all multiplet sizes.
