[i] Percent of sequencing attempts that yielded reads with an overall error rate <2.5%, an edited read length >100 bp, and free of E. coli and vector sequences.

[ii] Clones with at least one end sequence. Clone coverage was calculated assuming an average insert size of 197 kb for PRCI-23 library and 155kb for PCRI-24 library, and a genome size of 3 Gb.

[iii] Clones with both T7 and Sp6 end sequences (pairs). Clone coverage by pairs was calculated as described above. Total number of pairs, % of pairs in the database, and their coverage are shown.

[iv] Read length after sequences were trimmed. The average and standard deviation (S.D.) are shown.

[v] Average number of bases with phred QV ≥ 20 per sequence after sequences were trimmed. The average and S.D. are shown.

[vi] Percent of mBESs that contained repeats and percent of bases that were repeats, analyzed by RepeatMasker.

[vii] Percent of paired-end clones that had at least one end with ≥100 bp contiguous unique Q20 bases.

[viii] Percent of mBESs that were associated with the correct clone identifiers.
