Sequence assembly summary.

.Individual assembly statistics are shown for data from different sequencing technologies (454, Sanger, Solexa) and different species (O. exaltata, O. garganica, and O. sphegodes), where ‘Pooled 454’ refers to 454 data pooled from all three species. N50 length denotes the length-weighted median contig length of a given assembly. 1Singleton reads from 454 and Sanger data only. 2Out of these, 92 are Sanger reads.
