ZORRO is a hybrid sequencing technology assembler. It merges two sets of pre-assembled contigs into a more contiguous and consistent assembly. We have already tested Zorro with Illumina Solexa and 454 data sets of organisms varying from 3Mb to 100Mb. The main feature of Zorro is the treatment before and after assembly to avoid errors.
The ZORRO project is maintained by Gustavo Lacerda, Ramon Vidal and Marcelo Carazzole and was first used in this yeast assembly: Genome structure of a Saccharomyces cerevisiae strain widely used in bioethanol production
ZORRO needs better documentation and has not undergone sufficient testing as of now. If you want to discuss the pipeline you can join the mailing list: zorro-google group
