A good assembly would have a low number of contigs, a total length that makes sense for the species, and a high N50 value. Alist of kmers is automatically selected by SPAdes using the maximum read length of the input data, and each individual kmer contributes to the final assembly. This tutorial will serve as an example of how to use free and open-source genome assembly and secondary scaffolding tools to generate high quality assemblies ofbacterial sequence data. Comparative Genomics, from the Annotated Genome to Valuable Biological Information: A Case Study.

Sequencing of bacterial genomes using Illumina technology has become such a standard procedure that often data are generated faster than can be conveniently analyzed. Are you sure you want to create this branch? Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. One limitation of the GAGE-B data is that following its publication, assembly pipelines might be inadvertently tuned to produce high scores specifically on that dataset. HHS Vulnerability Disclosure, Help We present Bactopia, a pipeline for bacterial genome analysis, as an option for processing bacterial genome data.

For most microbes, closed genomes with accessory plasmids can be assembled with one touch using the default settings of our assembly pipeline. A major focus is the evolution and spread of bacterial pathogens (and antibiotic resistance) including the interactions that these pathogens have with their host and host-associated microbiota. To run AlignGraph we first need to convert the raw reads from fastq format to fasta format. This site needs JavaScript to work properly.
