The swings and roundabouts of a decade of fun and games with Research Objects

  1. 1. The swings and roundabouts of a decade of fun and games with Research Objects Professor Carole Goble The University of Manchester, ELIXIR-UK Software Sustainability Institute UK carole.goble@manchester.ac.uk 17th Italian Research Conference on Digital Libraries (IRCDL) 2021, 18th February 2021
  2. 2. I work at supporting Data Driven Research at three scales Across the research data lifecycle Life Sciences, Biodiversity social sciences, astronomy, digital libraries, chemistry etc EU Research Infrastructures

  4. 4. Methods De novo assembly and binning Raw reads from each run were first assembled with SPAdes v.3.10.020 with option --meta21. Thereafter, MetaBAT 215 (v.2.12.1) was used to bin the assemblies using a minimum contig length threshold of 2,000 bp (option --minContig 2000) and default parameters. Depth of coverage required for the binning was inferred by mapping the raw reads back to their assemblies with BWA-MEM v.0.7.1645 and then calculating the corresponding read depths of each individual contig with samtools v.1.546 (‘samtools view -Sbu’ followed by ‘samtools sort’) together with the jgi_summarize_bam_contig_depths function from MetaBAT 2. The QS of each metagenome-assembled genome (MAG) was estimated with CheckM v.1.0.722 using the lineage_wf workflow and calculated as: level of completeness − 5 × contamination. Ribosomal RNAs (rRNAs) were detected with the cmsearch function from INFERNAL v.1.1.247 (options -Z 1000 --hmmonly --cut_ga) using the Rfam48 covariance models of the bacterial 5S, 16S and 23S rRNAs. Total alignment length was inferred by the sum of all non-overlapping hits. Each gene was considered present if more than 80% of the expected sequence length was contained in the MAG. Transfer RNAs (tRNAs) were identified with tRNAscan-s.e. v.2.049 using the bacterial tRNA model (option -B) and default parameters. Classification into high- and medium-quality MAGs was based on the criteria defined by the minimum information about a metagenome-assembled genome (MIMAG) standards23 (high: >90% completeness and <5% contamination, presence of 5S, 16S and 23S rRNA genes, and at least 18 tRNAs; medium: ≥ 50% completeness and <10% contamination). Assignment of MAGs to reference databases Four reference databases were used to classify the set of MAGs recovered from the human gut assemblies: HR, RefSeq, GenBank and a collection of MAGs from public datasets. HR comprised a total of 2,468 high-quality genomes (>90% completeness, <5% contamination) retrieved from both the HMP catalogue (https://www.hmpdacc.org/catalog/) and the HGG8. From the RefSeq database, we used all the complete bacterial genomes available (n = 8,778) as of January 2018. In the case of GenBank, a total of 153,359 bacterial and 4,053 eukaryotic genomes (3,456 fungal and 597 protozoan genomes) deposited as of August 2018 were considered. Lastly, we surveyed 18,227 MAGs from the largest datasets publicly available as of August 201813,16,17,18,19, including those deposited in the Integrated Microbial Genomes and Microbiomes (IMG/M) database52. For each database, the function ‘mash sketch’ from Mash v.2.053 was used to convert the reference genomes into a MinHash sketch with default k-mer and sketch sizes. Then, the Mash distance between each MAG and the set of references was calculated with ‘mash dist’ to find the best match (that is, the reference genome with the lowest Mash distance). Subsequently, each MAG and its closest relative were aligned with dnadiff v.1.3 from MUMmer 3.2354 to compare each pair of genomes with regard to the fraction of the MAG aligned (aligned query, AQ) and ANI. https://doi.org/10.1038/s41586-019-0965-1 scripts, workflows, SOPs & datasets

Machine-processable Standards Low tech Graceful degradation Commodity tooling Incremental Multi-platform Technology Independent Keep it simple E X A M P L E S Developer friendliness A swing back to basics "just enough complexity / standards” sufficient extra benefits from what already exists… …without compromising the developer entry-level experience so much that they rather do their own thing.

  44. 44. Indeed. Linked Data is not enough. And sometimes its too much. Research Infrastructures: “digital technologies (hardware, software), resources (data, services, digital libraries, standards), comms (protocols, access rights, networks), people and organisational structures”
  45. 45. Tensions Research Infrastructures sit in the middle Academic Viewpoint Infrastructure Viewpoint Green field site Theoretical purity Use latest thing Proof of concept Sophistication Narrow developer audience Strive for super generic The end Exposing the tech Pre-existing platforms Practicality Use things that work Production Simplicity & Familiarity Wide developer audience Several specific is ok!

  47. 47. Just Enough Linked Data Just InTime simplifications rather than generalizations Retain benefits of Linked Data querying, graph stores, vocabularies, clickable URIs customization and conventions The stuff a developer needs documentation, examples, libraries, tools, community limited flexibility frees up developers familiarity is important Linked Data “exotics” there for when the time is right if needed by the right people +
  48. 48. Developer friendly ->Tooling, Libraries How can I use it?
