PMCID: 5754489
PMID: 29301880
DOI: 10.1128/genomeA.01399-17

[…] excluded, which resulted in 15 contigs with a combined total of 2,769,008 bp (n50, 324,561 bp) and with a g+c content of 32.72%. the largest contig was 753,539 bp long. contigs were extended using aligngraph, an algorithm for secondary de novo genome assembly, by aligning contigs and initial raw sequences to closely related references (). s. aureus n315 was identified as the closest related […]

[…] with b. anthracis; contigs that significantly aligned against human sequence were removed from the assembly. the contiguity of the assembly was then improved through a reference-guided approach with aligngraph (), using the ames ancestor as the reference. the assembly was polished with pilon v.1.3.0 (), resulting in 128 contigs. a dot plot analysis using mummerplot () was used to examine […]

[…] by assembling overlapping reads. a contiguous new assembly was generated as a result of significantly greater depth of sequencing thus avoiding gaps and the formation of multiple contigs. tools like aligngraph [] extend the use of paired-end sequencing reads to map to a closely related reference genome and creating contiguous or scaffolded assembly. schneeberger et al. [] used a hybrid approach […]

[…] cp012066, cp002496, cp007147, nc_011770, cp014948, and cp007399). specifically, an initial de novo assembly was generated using spades 3.10 and improved with ragout to inform contig order and aligngraph to close the gaps between scaffolds (). the assembly was improved through iterative remapping of the reads to the assembly using icorn2 to correct amplification errors and indel assembly […]

[…] may be improved by running it iteratively, in which the assembled genome is used as a reference in a next round of reference-guided de novo assembly [] or in other reference guided algorithms like aligngraph []., besides all these, our study shows that longer assemblies or assemblies with a high n50 or ng50 are not always the best assemblies (see fig. ). contigs or scaffolds maybe wrongly […]

[…] reads was performed using trimmomatic version 0.35 (). trimmed reads were assembled into contigs using the short read assembler spades (v.3.6.1) (), and secondary scaffolding was performed with aligngraph using published c. difficile reference sequences to guide the assembly (). quality assessment of finished assemblies was performed using quast (v.4.4) (). the assemblies […]
