To summarise our recent pre-print: Autocycler, the automated consensus assembler, when used with Nanopore long-read only Enterobacterales assemblies, produces more complete chromosomes and plasmids, with an accuracy comparable to hybrid assemblies.

Figure 2 from my recently pre-printed manuscript on the completeness and accuracy of Nanopore long-read only bacterial genome assembly for Enterobacterales. a) tile plot of chromosome circularisation, with assembler on the x-axis and sample on the y-axis, shows that the consensus long-read only assembler, Autocycler, circularised more chromosomes at 95% (87/92) than any other long-read or hybrid assembler. b) complex upset plot of plasmid reconstruction, showing that the best plasmid reconstruction was achieved by long-read assemblers incorporating the separate plasmid assembly tool, Plassembler, namely Autocycler and Hybracter, reconstructing >96% of plasmids.

Database choice matters even more than platform.
