JGI Genomic Single-cell Assembly Workflow
JIGSAW is a software package disigned to quality control and assemble genomic DNA sequences from single-cell bacterial and archaeal genomes. Amplification of singel-cell genomes using multiple displacement amplification technology presents challenges that magnify the amount of contaminants in the sample and produce non uniform depth of sequence coverage. these factors pose problems whan assembling the genomic data using currently availible short read assembles. The software addresses these problems by removing contaminants and normalizing the sequence read coverage prior to assemble. A hybrid assembly approach using two different open source genome assembly tools is then applied to piece together the DNA fragments. Additional reporting of QC metrics for the input sample and the genome assembly is provided for further analysis.
