DOI: 10.1038/s41598-017-18910-w

[…] settings. circlator was then used to locate and circularize complete chromosome and plasmids in the draft assembly. contigs representing the chromosome and plasmids were subsequently polished using nanopolish ( combined with bwa-mem. the polished genome of strain wch96200 was cured by quality-trimmed illumina reads using pilon with default settings, […]

[…] were designated as g group nomenclature ( samples that could not be assigned genotypes due to mismatches were re-analyzed for error correction. nanopolish pipeline was applied on input reads of these samples to check improvement on the base-level accuracy (loman et al., ). after polishing, consensus sequences were re-processed to assign […]

[…] a consensus sequence, using partial-order alignment (poa) software (). two rounds of error correction where conducted by the porefume pipeline. finally, the error corrected reads were polished using nanopolish () which uses the raw nanopore event data to increase the accuracy., we annotated the error corrected and polished sequencing data for the presence of antibiotic resistance genes using […]

[…] also sequenced on an illumina miseq instrument using the nextera library preparation protocol and miseq reagent kit v3 (illumina, san diego, ca, usa)., nanopore sequence reads were filtered using nanopolish v0.5.0 and assembled de novo concurrently with miseq reads using unicycler (). the assembly was polished with unicycler_polish using all sequence reads and scaffolded with links v1.8.5 () […]

[…] model which has been trained using in vitro methylated e. coli dna []. training models for r9 sequencing chemistries were kindly provided by jared simpson. we modified the original implementation of nanopolish 0.6.0 to allow methylation calling from different basecalling groups. for classification, the subset of cpg sites overlapping with sites covered by illumina 450k beadchip microarrays […]

[…] confirmed that these mismatches were not pcr artifacts, suggesting these errors might happen during the nanopore sequencing step. to explore whether such errors could be corrected, we ran the nanopolish pipeline to compute consensus sequences with improved base quality. after comparing these polished sequences with sequences obtained from sanger sequencing, we found that nanopolish […]

[…] two strategies, (i) the pilon version 1.21 hybrid method () to directly correct the assembly using the illumina reads by five iterative correction steps and (ii) a prior polishing of the sequence by nanopolish (), followed by four correction steps by pilon. the second method gave the best results, with approximately 2-fold fewer nucleotide variations than the illumina scaffolds, and the assembly […]
