1 Adjusted for 1252 "NoFp" 0 band clones only (includes all clones with > = 1 band).

2 Adjusted for all 0–4 band clones, contamination-suspect clones and most high band number (>65) clones.

3 All repeat contigs with greater than 25 clones are represented in contig #'s 9000 and greater.

4 Includes 265 repeat contigs that have 15–19 clones (contig #'s 8000 – 8264) and 168 contigs that have 20–24 clones in contig #'s 9000 and greater.

5 Based on 4.0 kbp per unique band, for 2,208 contigs containing ~68 unique bands in 15 clones, 264 duplicated region contigs containing ~68 unique bands in 30 clones 15,840 unique bands and 406 highly repeated region contigs containing ~68 unique bands in 60 clones, 48,720 unique bands.

6 Based on 4.0 kbp per unique band.
