{"doi":"10.21926/obm.genet.2402239","title":"Reflective Evaluation of Next-Generation Sequencing Data during Early Phase Detection of the Delta Variant","abstract":"During the SARS-CoV-2 pandemic, next-generation sequencing (NGS) technologies like the Ion Torrent S5 and Illumina MiSeq, alongside advanced software, improved genomic surveillance in South Africa. This study analysed anonymized samples from the Eastern Cape using Genome Detective and NextClade, showing Ion Torrent S5 and Illumina MiSeq success rates of 96% and 94%, respectively. The study focused on genomic coverage (above 80%) and mutation detection (below 100), with the Ion Torrent S5 achieving 99% coverage compared to Illumina MiSeq's 80%, likely due to different primers used in amplification. The Ion Torrent S5 was more effective in sequencing varied viral loads, whereas Illumina MiSeq had difficulties with lower loads. Both platforms were adept at identifying clades, successfully differentiating between Beta (<45%) and Delta variants (<30%), despite minor discrepancies in assignments due to Illumina MiSeq's lower coverage, leading to a failure rate of up to 6%. Manual library preparation showed similar sample processing and clade identification capabilities for both platforms. However, differences in sequencing duration (3.5 vs. 36 hours), automation level, genomic coverage (80% vs. 99%), and viral load compatibility were noted, highlighting each platform's unique advantages and challenges in SARS-CoV-2 genomic surveillance. In conclusion, the Illumina MiSeq and Ion Torrent S5 platforms are both efficacious in executing whole-genome sequencing (WGS) via amplicons, facilitating precise, accurate, and high-throughput examinations of SARS-CoV-2 viral genomes. However, it is important to note the existence of disparities in the quality of data produced by each platform. Each system offers unique benefits and limitations, rendering them viable choices for the genomic surveillance of SARS-CoV-2.","journal":"OBM Genetics","year":2024,"id":498101,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":0.0,"corpus_rank":10062,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.6559,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":66.6667,"fair_percentile":86.48731274839498,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":621554,"name":"Derek Tshiabuila","orcid":"0000-0001-5221-2126","position":1,"is_corresponding":false},{"id":840316,"name":"Yajna Ramphal","orcid":null,"position":2,"is_corresponding":false},{"id":282131,"name":"Jennifer Giandhari","orcid":"0000-0002-2944-4583","position":3,"is_corresponding":false},{"id":365045,"name":"Carel J. van Heerden","orcid":"0000-0003-1786-7527","position":4,"is_corresponding":false},{"id":536857,"name":"Cheryl Baxter","orcid":"0000-0002-6033-7655","position":5,"is_corresponding":false},{"id":838677,"name":"Stephanie van Wyk","orcid":"0000-0002-2655-8518","position":6,"is_corresponding":false},{"id":282132,"name":"Sureshnee Pillay","orcid":"0000-0001-9288-7996","position":7,"is_corresponding":false},{"id":634082,"name":"Oluwakemi Laguda-Akingba","orcid":"0000-0002-1225-8098","position":8,"is_corresponding":false},{"id":282133,"name":"Eduan Wilkinson","orcid":"0000-0002-2503-9441","position":9,"is_corresponding":false},{"id":69666,"name":"Richard Lessells","orcid":"0000-0003-0926-710X","position":10,"is_corresponding":false},{"id":279259,"name":"Túlio de Oliveira","orcid":"0000-0002-3027-5254","position":11,"is_corresponding":false},{"id":838675,"name":"Upasana Ramphal","orcid":"0000-0002-2441-3868","position":0,"is_corresponding":true}],"reference_count":48,"raw_metadata":null,"created_at":"2026-07-19T02:09:38.543544Z","pmid":"41048582","pmcid":"PMC12494147","fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":72.2222,"fair_a":75.0,"fair_i":60.0,"fair_r":33.3333,"fair_zscore":1.2752,"fair_rationale":{"fair_score":66.67,"has_llm":true,"taxonomy_version":"fair_taxonomy_v5","dimensions":{"F":{"name":"Findable","score":72.22,"criteria":[{"key":"f_dataset_pid","label":"Persistent identifier for the data","kind":"llm","weight":2.0,"fraction":1.0,"verdict":"yes","evidence":"Epidemic data is freely available on the open-source GISAID database and accessed using the GISAID Identifier: EPI_SET_230203ym; doi: https://doi.org/10.55876/gis8.230203ym.","grounded":true,"rationale":"A DOI (10.55876/gis8.230203ym) is provided for the epidemic data, which is a persistent identifier scheme.","anchors":["RDA-F1-01D — FAIR Data Maturity Model: 'Data is identified by a persistent identifier' (priorit","RDA-F1-02D — FAIR Data Maturity Model: 'Data is identified by a globally unique identifier'","FsF-F1-02D — F-UJI/FAIRsFAIR: 'Data is assigned a persistent identifier'"],"scored":true,"signal":null},{"key":"f_repository_named","label":"Named repository","kind":"llm","weight":2.0,"fraction":1.0,"verdict":"yes","evidence":"All the raw sequence data generated for this research are available publicly in the NCBI Sequence Read Archive (project no.
