## Description

The Ciona genome shotgun assembly was constructed with the DOE Joint Genome Institute (JGI) assembler, JAZZ, paired end sequencing reads at a coverage of 8.2X produced at the JGI. The assembly contains 116.7 million base pairs of nonrepetitive sequence in 2,501 scaffolds greater than 3 kb. Half of this (60 Mbp) is assembled into 117 scaffolds longer than 190 Kbp; 85% of the assembly (104.1 Mbp) is found in 905 scaffolds longer than 20 kb. Gene modeling and analysis were performed at the JGI.

## Methods

The alignments were made with blat in translated protein mode requiring two nearby 4-mer matches to trigger a detailed alignment.

## Credits

These data were freely provided by the JGI for use in this publication/correspondence only.

The 1.0 draft from http://genome.jgi-psf.org/ciona4/ciona4.info.htm was used in these alignments.
