Use all subreads for polishing (Falcon_unzip 1.1.5) We used to use only 1 per zmw, same as assembly typically. Gcpp instead of GenomicConsensus for polishing (Falcon_unzip 1.2.0) Feature Highlights from February - April 2019 Releases See the latest release notes for the bioconda distribution here.

Mappin the HiC data in order to correctly separate the unzipped regions into pahses.įALCON and FALCON-Unzip are now compatibile with HiFi data. Additional information is needed to phase the haplotypeīlocks with each other such as Hi-C, see FALCON-PhaseįALCON-Phase involves processing the FALCON-Unzip contigs into unzipped blocks (haplotigs pairs) and collapsed haplotypes and then Originate from different parental haplotypes. Thus, in part C) of the figure below, haplotig_1 and haplotig_2 may It is important to note that while individual haplotype blocks are phased, phasing does The unzip process will extend haplotype phasing beyond “bubble” regions, increasing the amount of phasedĬontig sequence. Polishing greatly increases base quality of the assembly.įor more complex genomes assembled with FALCON, “bubbles” in the contig-assembly graph that resultįrom structural variation between haplotypes may be resolved as associate and primary contigs. In the next round of HGAP, the preads are aligned to each other and assembled into genomic contigs.Īssembly is typically followed by a round of polishing where all raw PacBio subreads are aligned to the draftĬontigs and genomic consensus is performed.
We refer to these as pre-assembled reads and they can also be thought of as “error corrected” reads. Shorter reads are aligned to the seed reads, in order to generate consensus sequences with high accuracy. The selection of seed reads or the longest reads in the dataset (user-defined length_cutoff). The first round is pre-assembly or error correcction of the long reads. Hierarchical Genome Assembly Process (aka non-hybrid PacBio assembly)Īssembly with PacBio data uses the hierarchical genome assembly process (HGAP).
Shreddage 3 unzip error software#
A stand-alone version 1 of the software is available through our co-developer, Phase Genomics. This method maps HiC data to the FALCON-Unzip assembly to fix phase switches between haplotigs within primary contigs. It then produces a set of partially-phased primaryĬontigs and fully-phased haplotigs which represent divergent haplotypes. It takes the contigs from FALCON and phases the readsīased on heterozygous SNPs identified in the initial assembly. Each a-contig isĪssociated with a homologous genomic region on an p-contig.įALCON-Unzip is a true diploid assembler. Set of associate contigs (a-contigs) which represent divergent allelic variants. FALCON produces a set of primary contigs (p-contigs) as the primary assembly and a The hierarchical genome assembly process (HGAP) and is optimized for large genome assembly though microbial
FALCON is a diploid-aware assembler which follows Single-Molecule Real-Time (SMRT) sequences. FALCON and FALCON-Unzip are de novo genome assemblers for PacBio long reads, also known as
