supervised plant collection. The purified sample was size selected using the Blue Pippin with a dye-free, 0.75% agarose cassette and U1 marker (Sage Science, BUF7510, Mulgrave, Victoria, Australia) and the 0.75% DF Marker U1 high-pass 30â40Â kb vs3 run protocol, with a BPstart cut-off of 35,000 bp. performed Illumina, ONT and PacBio assemblies and assembly evaluation. Therefore, depending on the assembler and the polisher used, the number of recommended polishing iterations might be different. Therein lies another sizable risk for Illumina's business: consumables. Removing the cold chain would make reading the genetic alphabet vastly more accessible, while greatly reducing the cost of sequencing -- without the need to build instruments the size of, ironically enough, a refrigerator. For both gap-filled assemblies, the total assembly length increased correspondingly to â¼895 and 770 Mb for scaffolds larger than 10Â kb. Besides, we are one of the largest PacBio Sequencing service provider in the world with > 10 units of Sequel Sequencers. RNA was digested by adding RNase solution (10Â mg/mL), the contents gently mixed by inverting the tubes followed by incubation at room temperature for 10Â min. Interestingly, the long-read polishing step did not improve the completeness of the Redbean, Flye, and Raven assemblies and similar or slightly better results were obtained after short-read polishing alone. The median insert size was 713Â bp. The ONT + Illumina assemblies (except MaSuRCA) were polished with the ONT long reads using Racon and Medaka followed by the Illumina short reads using 1 iteration of NextPolish. Furthermore, and in collaboration with more of the conferences AllSeq offers discount codes for the conference ticket and other benefits for when you are about to determine which […] Figure S3: Number of mismatches and indels identified in the long-read assemblies as compared to the Illumina short-read assembly generated by SPAdes. These contigs were transferred to the haplotigs set. Diploid de novo genome assembly of PacBio reads was performed with FALCON v1.3.0 (FALCON, RRID:SCR_016089)  using a genome size of 780 Mb, a length cut-off of 40,740Â bp, and a seed read coverage cut-off of 30. The pulverized leaf tissue was stored at â20Â°C until further required for DNA extraction. For each species, the PromethION platform was used to generate 30–45× sequence coverage, and the Illumina platform was used to generate 50–160× sequence coverage. Additionally, we found that polishing the ONT assembly with the Illumina short reads was required to reach a similar genome completeness to that of the PacBio assembly. Instruments; Kits & Reagents; Selection Tools; Software & Analysis; Services; Popular Products; Explore All Products. Oxford Nanopore's approach takes long genetic sequences, passes them through a single protein channel (a "nanopore"), and reads the alphabet in large chunks by measuring voltage changes across the channel. Which sequencer should you buy. Polishing decreases the number of missing BUSCOs but increased the number of duplicated BUSCOs for the Redbean, Flye, and Raven assemblies (Supplementary Table S10). This work was funded by the Genome Innovation Hub, Office of Research Infrastructure, The University of Queensland. reviewed the manuscript. Oxford Nanopore MinIon & PromethIon vs Illumina, LifeTech, etc. That could be a huge problem down the road -- one exposed courtesy of nanopore sequencing. Products. To paraphrase Quentin Tarantino, you buy one of these “When you absolutely, positively got to sequence every person in the room, accept no substitutes”. wrote the manuscript with input from all authors. In particular, the Canu contig N50 significantly increased from 706Â kb (21Ã) to 1.43 Mb (32Ã). Founded in 1993 by brothers Tom and David Gardner, The Motley Fool helps millions of people attain financial freedom through our website, podcasts, books, newspaper column, radio show, and premium investing services. Rob Edwards from San Diego State University describes Oxford Nanopore MinION sequencing It contains 48 flow cells that can be run individually or in parallel. Valentine Murigneux, Genome Innovation Hub, The University of Queensland, Brisbane, QLD 4072, Australia. The quality of the DNA sample was assessed in NanoDrop, Qubit, and the Agilent 4200 TapeStation system. The data correspond to â¼84Ã coverage of the estimated 780 Mb genome size. The resulting Flye assembly showed a similar size of 764 Mb, a lower contiguity (contig N50 = 1.26 Mb), and a similar genome completeness (94.7% complete BUSCOs) as the 84Ã coverage assembly (Fig.Â 1, Supplementary S2 and Table S8). All DNA sequencing methods must deliver on metrics including cost, time to results, and the accuracy of those results. Furthermore, PacBio recently released an amplification-based ultra-low DNA input protocol starting with 5Â ng of high molecular weight DNA. We used the material generated by rca for nanopore sequencing on the minion. We are one of the Illumina certified provider and one of the main partner of Illumina Genome Network in China. Next, these transposon-inserted DNA molecules were hybridized with barcode-labelled 3-Î¼m diameter magnetic beads containing oligonucleotide sequences with a PCR primer annealing site, an stLFR barcode, and a sequence complementary to the capture sequence on the transposon. Next, long-range scaffolding approaches such as chromosome conformation capture (Hi-C, Chicago) or physical maps technologies (optical map, restriction map) are required to order and orient the assembled contigs into chromosome-length scaffolds . Low cost of Illumina cost is largely down to economies of scale. At illumina our goal is to apply innovative technologies to the analysis of genetic variation and function making studies possible that were not even imaginable just a few years ago. The length and sequence quality delivered by the available sequencing platforms has continued to improve. The library was prepared for sequencing according to the SMRT Link sample set-up calculator, following the standard protocol for Diffusion loading with AMPure PB bead purification, using Sequencing Primer v3, Sequel Binding Kit v3.0, and the Sequel DNA Internal Control v3. Instruments. The PromethION is the sequencing device of Oxford Nanopore Technologies, capable of delivering multiple terabases of data from a single run in real time. The stLFR library construction requires â¥10Â ng of high molecular weight DNA. (A) ONT assemblies before and after Illumina short-read polishing using 1 iteration of NextPolish (Flye, Canu, Raven, Redbean) and MaSuRCA hybrid assembly; (B) PacBio assemblies before and after Illumina short-read polishing using 1 iteration of NextPolish (Falcon, Flye, Canu, Raven, Redbean) and MaSuRCA hybrid assembly; (C) BGI stLFR assemblies before and after gap filling using ONT or PacBio data and after polishing with stLFR reads using 1 iteration of NextPolish. The purified gDNA (10 Î¼g) was treated with Exonuclease VII, followed by a DNA damage repair reaction, an end-repair reaction, and purification with AMPure PB beads. When all the reads were incorporated, the assemblies generated using the PacBio and ONT data were comparable in terms of assembly contiguity (contig N50 of â¼1.5 Mb) and genome completeness (95% of complete BUSCOs). 75 … The input requirement for DNA and RNA ranges from 1 ng to 100 ng, depending on the application needs. For instance, short-read polishing using NextPolish used less memory than Pilon while providing similar results. As expected, a reduced number of mismatches and indels was identified in the assemblies as compared to the Illumina assembly (Supplementary Fig. ), and Complete Genomics (E.A., Q.M., R.D., B.A.P.) Furthermore, the assembly generated by Supernova was phased. This is a rare species that is a close relative of the macadamia nut recently domesticated in Hawaii and Australia. V.M. The assembly was highly fragmented, with a contig N50 of 23.9Â kb. The ONT cost includes library preparation (400 USD) and sequencing on 1 PromethION flow cell (2,050 USD) and 1 MinION flow cell (820 USD). Employees of BGI (W.T., I.H., Q.Y., B.Y., O.W., M.X, P.W. The genome assembly of M. tetraphylla was also recently produced using a combination of long-read Oxford Nanopore Technologies (ONT) and short-read Illumina sequence data (751 Mb, 4,335 contigs, N50 = 1.18 Mb) . S3 and Table S6). supported stLFR analyses. performed ONT library preparation and sequencing. Using a liquid nitrogenâcooled spatula, frozen pulverized leaf tissue (3Â g) was added to 50-mL tubes (Corning or Falcon) containing warm (40Â°C) nuclear lysis buffer (8Â mL) and 5% sarkosyl solution (5Â mL). This is a flowering plant (angiosperm) in the Proteaceae family that is basal to the large eudicot branch of the flowering plant phylogeny . Ultra-high throughput, on-demand nanopore sequencing, for you or as a service. For the ONT sequencing, we combined the results of 1 PromethION and 1 MinION flow cell, generating a total of 24.9 Gb of data with a read length N50 of 27.8Â kb (TableÂ 1). Finally, the estimatedk-mer assembly completeness increased in the gap-filled assemblies from 95.8% to 96.7% (ONT) and 97.4% (PacBio) (Supplementary Table S7). In fact, the first such products can withstand temperatures of over 100 degrees Fahrenheit for over one month. stLFR generated 738 million 100-bp paired-end reads. Brozynska Â M, Furtado Â A, Henry Â RJ. The DNA material requirements to prepare the sequencing library are another important parameter to consider when choosing a sequencing technology. The PromethION flow cell and the MinION flow cell generated 23.2 and 1.7 Gb of data, respectively, with a read length N50 of 28.5 and 16.6Â kb and a median read quality of 6.3 and 8.9. The silicon-based nanopore approach has other advantages over Illumina's current approach, including one notable consideration for the future of DNA sequencing: size. Nanopores read the length of DNA or RNA presented to them — from short to ultra-long (longest >4 Mb) Dimensions. The stLFR sequencing libraries were prepared using the MGIEasy stLFR Library Prep Kit (MGI, Shenzhen, China) following the manufacturerâs protocol. But it's still challenged by accuracy. ONT PromethION and PB Sequel II platforms, respectively. The adapter-ligated DNA sample was quantified using QubitTM dsDNA HS Assay Kit (Thermo Fisher Scientific, Scoresby, Victoria, Australia). Quick j grubaugh n pullan s. Compare features and technical specifications for all of our products. Single-molecule real-time (SMRT) sequencing, developed by PacBio, can generate reads in the tens of kilobases using the continuous long-read sequencing mode, thus enabling high-quality de novo genome assembly. ONT read length and quality were calculated with NanoPlot v1.22 . It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. *Assembly polished using Illumina reads. The library was sequenced on an SP flow cell (14%) of the Illumina Nova Seq 6000 sequencing platform (Ramaciotti Centre, University of New South Wales, Australia) using the paired-end protocol to produce 112 million 150-bp reads in pairs, an estimated 43Ã genome coverage. There were important differences in the assembly run time and memory usage depending on the tool used. L.J.M.C. Market data powered by FactSet and Web Financial Group. Put another way: If a low-cost, fast, and accurate DNA sequencer could hook up to a smartphone, what other applications would become accessible? Below is the list of our ongoing NGS promotions: Meet the New Sequel II at DNA Link Human Exome at $239 mRNA-Seq at $199 Non-coding, not to be missed – total RNA-Seq An estimation of computational costs based on Amazon EC2 on-demand pricing is provided in Supplementary Table S2. Since the sequence data were generated, the PacBio SMRT platform has transitioned from the Sequel I to the Sequel II instrument, with an 8-fold increase in the data yield. Bankevich Â A, Nurk Â S, Antipov Â D, et al.Â Â, Weisenfeld Â NI, Kumar Â V, Shah Â P, et al.Â Â. Xu Â M. BGI-Qingdao/TGSGapFiller. The lawsuits focus on ONT’s MinION and PromethION devices. B.Y. Accession numbers are as follows: BGI (SRR11191908), PacBio (SRR11191909), ONT PromethION (SRR11191910), ONT MinION (SRR11191911), and Illumina (SRR11191912). Q.Y. The total assembly length is plotted against the contig N50 for each assembler and sequencing coverage. Results obtained from combining long-read technologies or short-read and long-read technologies are also presented. Why not 500?' In fact, out of all the Illumina instruments, the MiSeq is best suited for amplicon-seq, 16S and other low diversity read based applications. The Illumina short-read assembly was generated using more accurate short reads as compared to long reads; therefore it contained fewer base errors. The Illumina library was prepared using the Nextera Flex DNA kit. The histograms of the k-mer occurrences were processed by GenomeScope (GenomeScope, RRID:SCR_017014) , which estimated a genome haploid size of 653 and 616 Mb with â¼71% and 74% of unique content and a heterozygosity level of 0.65% and 0.77% from Illumina and BGI reads, respectively. Illumina has been publicly dismissive of Oxford Nanopore and of nanopore sequencing due to the technique's lower accuracy, but accuracy is not the only metric that matters. Illumina filed the lawsuits to protect its investment and patent rights in this technology. https://github.com/MGI-tech-bioinformatics/SuperPlus/blob/master/split_barcode/split_barcode_PEXXX_42_unsort_reads.pl. PromethION 24/48. Skip to content. At a much larger scale, PromethION offers the same technology for real-time, long-read, direct DNA and RNA sequencing as MinION and GridION. For Redbean, Flye, and Canu, the estimated genome size was set to 780 Mb . The supernatant was transferred into fresh 50-mL tubes and the chloroform extraction repeated twice. And the tiny competitor recently announced a realistic path toward making nanopore sequencing the fastest and cheapest, as well as the most accurate, approach in the industry. Assembly completeness was also estimated by comparing the k-mer spectrum of the polished assemblies to the k-mer spectrum of the Illumina short reads (Supplementary Table S7 and Fig. when a company is so dominant it can sell expensive instruments and then dictate what can be sequenced surely that is a problem for users. probably not because of the rumoured IPO or the minION but because of the promethion as a directly competitive device to their suite. After adapter and polyG tail trimming, short reads were assembled using the SPAdes software. The Flye assembly was highly contiguous (contig N50 = 1.47 Mb) and the smallest in size (767 Mb). Overview Purchasing info Output and price per Gb Sample prep Specifications Platform Application. But because Oxford Nanopore's devices are intended for use both inside and outside the lab, it has been developing novel reagents that don't require cold storage. S2 and S3, Tables S4 and S5). The size of the instrument hasn't been an issue in DNA sequencing to date because most customers are hospitals or genetic testing companies with dedicated lab space. According to Bioeconomy Capital, biopharma comprised only 32% of all revenues in the American bioeconomy in 2016. We report a comparison of 3 long-read sequencing datasets generated from the same plant DNA sample. prepared the sample. We also demonstrated that stLFR could be used as a complementary technology to ONT. When biotech investors talk about the future of DNA sequencing, they inevitably focus on industry leader Illumina (NASDAQ:ILMN). Illumina sequencing generated 112.5 million 150-bp paired-end reads, which correspond to â¼41Ã coverage of the genome. The scaffold N50 slightly decreased by 0.02 or 0.04 Mb due to the adjustment of the estimated gaps. The Sequel (and the PromethION) actually challenge Illumina – because in an era of cheap, long read sequencing, Illumina becomes a genotyping platform, not a sequencing platform. AllSeq’s Conference Lists are continually updated lists, overviews and access points for scientific conferences, that allows you to know what conferences are going on where and when. Raven was the only tool run on a GPU-accelerated server and it was the fastest assembler, followed by Redbean and Flye. Young leaves were harvested, placed in on ice in bags, and within 3Â h snap-frozen under liquid nitrogen and stored at â20Â°C until further processed for tissue pulverization using either a mortar and pestle or the Mixer Mill as outlined below. and P.W. A total of 5,065 scaffolds were larger than 10Â kb, with a total length of 752 Mb and N50 of 3.54 Mb for scaffold and 35.6Â kb for contig (TableÂ 2). Third-party reagents NEBNext end repair/dA-tailing Module (E7546), NEBNext formalin-fixed paraffin-embedded DNA Repair Mix (M6630), and NEB Quick Ligation Module (E6056) were used during library preparation. Genome Innovation Hub, The University of Queensland, Institute for Molecular Bioscience, The University of Queensland. to 35 (ASIC II code = #) to meet the 10X Genomicsâ quality system. Die Sequenzierung von DNA/RNA mittels Nanoporen stellt eine von zwei kommerziell verfügbaren long-read single molecule Sequenziertechniken, auch als third-generation sequencing (TGS) bezeichnet, dar. Here, we report a comparison of 3 long-read sequencing technologies applied to the de novo assembly of a plant genome, Macadamia jansenii. Conserved BUSCO gene analysis revealed that the stLFR assembly contained 88.3% of complete genes from the eudicotyledons dataset (Fig.Â 3). The PacBio + Illumina assemblies (except MaSuRCA) were polished with the Illumina short reads using 1 iteration of NextPolish. It is mission critical for us to deliver innovative, flexible, and scalable solutions to meet the needs of our customers. We propose updating this comparison regularly with reports on significant iterations of the sequencing technologies. S2). At the time of sequencing, the cost associated with each method was significantly different, but continuous improvements in technologies have resulted in greater accuracy, increased throughput, and reduced costs. designed stLFR experiments and performed stLFR analyses. Table S1: Technical specifications of computing clusters, Table S2: Estimation of computational costs based on Amazon EC2 on-demand pricing as of 19 September 2020, Table S3: Illumina genome assembly statistics using SPAdes assembler, Table S4: ONT genome assembly statistics using Redbean, Flye, Canu, Raven, and MaSuRCA assemblers, Table S5: BUSCO genome completeness assessment of ONT long-read assemblies (Redbean, Flye, Canu, Raven) and hybrid assembly (MaSuRCA), Table S6: QUAST assembly statistics using the Illumina short-read assembly as the reference genome, Table S7: Â k-mer completeness of ONT, PacBio, and stLFR assemblies, Table S8: PacBio genome assembly statistics using Redbean, Flye, Falcon, Canu, Raven, and MaSuRCA assemblers, Table S9: PacBio genome assembly statistics and genome completeness assessment before and after Purge Haplotigs, Table S10: BUSCO genome completeness assessment of PacBio long-read assemblies (Redbean, Flye, Falcon, Canu, Raven) and hybrid assembly (MaSuRCA), Table S11: BGI stLFR genome assembly statistics using Supernova assembler and TGS-GapCloser gap-closing software. M. jansenii has not been domesticated, and its small and bitter nuts are obstacles that restrict simple introgression in breeding. The supernatant was carefully transferred to fresh 2-mL tubes and the quality checked on a spectrophotometer, and the DNA was resolved on a 0.7% agarose gel. Aligning the PacBio assemblies to the M. integrifolia assembly identified a higher number of misassemblies in the Canu asssembly (n = 38,800) as compared to the other assemblies (n = 21,000â27,000). Maxx has been a contributor to Fool.com since 2013. To meet the memory requirement of the assembler, the barcodes with <10 reads were removed from the dataset. Read sequences were then converted to 10X Genomics format by BGIâs inhouse software, which contains 3 steps: (i) Change the format of readsâ head from MGI to Illumina. S2) and a decrease in the number of indels (Supplementary Table S6 and Fig. Long reads from PacBio and ONT were prepared using 2 or 3 alternative strategies, respectively: Filtered: ONT long reads were adapter-trimmed using Porechop v0.2.4 (Porechop, RRID:SCR_016967) . Raw Illumina and BGI short reads were adapter-trimmed using Trimmomatic v0.36 (Trimmomatic, RRID:SCR_011848)  (LEADING:3 TRAILING:3 SLIDINGWINDOW:4:15 ILLUMINACLIP:2:30:10 MINLEN:36). TGS-GapCloser v1.0.0 (TGS-GapCloser, RRID:SCR_017633) [45,46] was used to fill the gaps between contigs within same scaffolds, and this process was performed under the use of error-corrected ONT or PacBio data by Canu. Several assemblers were benchmarked in the assembly of Pacific Biosciences and Nanopore reads. The decrease in coverage did not affect the Raven assembly contiguity (contig N50 = 894Â kb). However, investors who dare to peek over the horizon might notice that the industry appears to be headed in a different direction. This step ensured that the temperature of the coarsely ground tissue was maintained close to â80Â°C while allowing the liquid nitrogen to evaporate off completely, an essential requirement for the pulverization step. Sequencing Platforms; Microarray Scanners; IVD Instruments ; All Instruments. Illumina's approach takes tiny fragments of genetic sequences and reads the alphabet approximately letter by letter using a light-based method (the "single-base accuracy" Samad refers to). Chloroform (10Â mL) was added to the tubes and gently mixed by inverting the tubes 50Â times. Assembly statistics were computed using QUAST v5.0.2 (QUAST, RRID:SCR_001228)  with a minimum contig length of 10Â kb and the parameters --fragmented --large. Digging into the Illumina Lawsuit vs. Oxford Nanopore ... time until they can think what to do next. Dubbed the “Illumina killer”, it’s the last product that has everyone excited. Dr. M.X. The DNA was then stored at â20Â°C until used for sequencing. Sequencing was performed using the PacBio Sequel I (PacBio Sequel System, RRID:SCR_017989) (software/chemistry v6.0.0). For ONT sequencing, it is recommended to obtain â¥1â2 Î¼g of high molecular weight DNA. Genome coverage estimates were computed on the basis of the number of reads used in assembly and an estimated genome size of 780 Mb. The PromethION library was prepared from 1,200Â ng SRE-treated DNA using the ligation sequencing kit (SQK-LSK109, ONT, Oxford, UK). But shareholders shouldn't get comfortable. That's not a problem for instruments with access to utilities and freezers (such as in a hospital), but it's a deal-breaker for sequencing instruments used in the field (say, a jungle). Illumina Sues Oxford Nanopore for Patent Infringement. The supernatant was discarded and the DNA pellet was washed of any co-precipitated salts by adding 10Â mL of 70% ethanol and incubating the tubes at room temperature for 30Â min. The publicly available reference genome of M. integrifolia v2 (Genbank accession: GCA_900631585.1)  was used as the reference genome for QUAST. PromethION is available in two models: PromethION 24 (P24) and PromethION 48 (P48), which can respectively operate up to 24 and 48 flow cells at once. The latest instrument Wall Street is clamoring over, the NovaSeq, is over five feet tall and weighs over 1,000 pounds. We have generated sequencing data using Pacific Biosciences (Sequel I), Oxford Nanopore Technologies (PromethION), and BGI (single-tube Long Fragment Read) technologies for the same sample. The DNA was dissolved by adding 100 Î¼L of TE buffer and then adding incremental 50 Î¼L of TE buffer where required. We also performed gene expression level quantification and differentially expressed gene (DEG) analysis, using the data obtained from PromethION and Illumina sequencers. Products Learn Company Support Recommended Links. and L.J.M.C. Sequencing of wild crop relatives is urgent because many populations are critical to diversification of crop genetics to ensure food security in response to climate change  but are also threatened with extinction due to changes in land use or climate . The 3 long-read technologies produced highly contiguous and complete genome assemblies. was supported by a Discovery Project with grant number DP170102626 awarded by the Australian Research Council. For high molecular weight DNA (HMW-DNA) samples, read lengths of several hundred kb can be reached with ultra-long-read protocols.The Nanopore sequencing data greatly enable de novo genome assemblies and structural genomic variant and … In addition, the genome completeness was improved in the gap-filled assemblies, with BUSCO detecting 4.8% (ONT) and 5.8% (PacBio) more complete genes. This is because there's a lower noise floor (i.e. The specimen of M. jansenii used in these experiments was a clonally propagated ex situ tree planted in the arboretum at Maroochy Research Facility. 1M reads for Nanopopore vs 40M reads for Illumina). The stLFR cost is estimated on the basis of the number of raw reads subsequently used in assembly (â¼90 Gb) and includes library preparation (400 USD) and sequencing (8 USD per Gb). Here we compare Sequel I (PacBio), PromethION (ONT), and stLFR (BGI) data for the same DNA sample and evaluate the quality of the assemblies that can be generated directly from these datasets. PacBio SMRT sequencing has a high genomic DNA input requirement of 5â20 Î¼g of high molecular weight DNA for standard library protocol depending on the genome size but the PacBio low DNA input protocol has reduced this requirement to as low as 100Â ng per 1 Gb genome size . That said, the stLFR assembly was more fragmented than the other long-read technologies. The "cold chain" also comprises a great majority of the overall cost of sequencing: Illumina's $1,000 human genome price tag includes $797 in reagent expenses. The excess oligonucleotides and transposons were then digested with exonuclease and the transposase enzyme was denatured with sodium dodecyl sulfate. The total assembly length is plotted against the contig N50 for each assembler and sequencing dataset. Illumina have nothing in the pipeline in terms of a nanopore sequencer but just a HiSeq 50 or 100 and as always, the MinION is ruining their best laid plans. However, the characteristic small tree size, being 50% smaller than commercial cultivars, is of interest for use in high-density orchard design and it is being trialled as a rootstock for this purpose . The Redbean assembly was the most fragmented (contig N50 = 649Â kb) and the least complete (89% complete BUSCOs). V.M. Compare features and technical specifications for all of our products. In particular, the number of indels was greatly reduced after polishing with NextPolish as compared to Pilon (Flye: 48Â vs 83 indels per 100Â kb, Canu: 68Â vs 108, Raven: 49Â vs 85, Redbean: 42Â vs 76, Supplementary Table S6). Gap filling for stLFR assembly using error-corrected ONT or PacBio reads. Read length. GPU-accelerated computing greatly reduced the computing time for some tools such as Racon, Medaka, or Raven.
