A tool to circularize genome assemblies.
PLEASE NOTE: we currently do not have the resources to provide support for Circlator, so please do not expect a reply if you flag any issue. Apologies for the inconvenience.
Circlator will attempt to identify each circular sequence and output a linearised version of it. It does this by assembling all reads that map to contig ends and comparing the resulting contigs with the input assembly.
For how to install Circlator, please see the Circlator website.
Usage: circlator <command> [options] <required arguments> To get minimal usage for a command use: circlator command To get full help for a command use one of: circlator command -h circlator command --help Available commands: all Run mapreads, bam2reads, assemble, merge, clean, fixstart mapreads Map reads to assembly bam2reads Make reads from mapping to be reassembled assemble Run assembly using reads from bam2reads merge Merge original assembly and new assembly made by assemble clean Remove small and completely contained contigs from assembly fixstart Change start position of circular sequences minimus2 Run the minimus2 based circularisation pipeline get_dnaa Download file of dnaA (or other of user's choice) genes progcheck Checks dependencies are installed test Run Circlator on a small test set version Print version and exit For more information on how to use Circlator, please see the Circlator wiki page.
