Although multiple omics datasets on the YMC are available, a unified landscape for this process is missing. To address this gap, we integrated multi-omics datasets by singular value decompositions (SVDs), which stratify each dataset into two levels and define four eigen-phases: primary 1A/1B and secondary 2A/2B. The eigen-phases occur cyclically in the order 1B, 2A, 1A, and 2B, demonstrating an interplay of induction and repression: one eigen-phase induces the next one at a different level, while represses the other one at the same level. Distinct molecular characteristics were identified for each eigen-phase. Novel ones include the production and consumption of glycerol in eigen-phases 2A/2B, and the opposite regulation of ribosome biogenesis and aerobic respiration between 2A/2B. Moreover, we estimated the timing of multi-omics: histone modifications H3K9ac/H3K18ac precede mRNA transcription in ∼3 min, followed by metabolomic changes in ∼13 min. The transition to the next eigen-phase occurs roughly 38 min later. From epigenome H3K9ac/H3K18ac to metabolome, the eigen-entropy increases.

The recent work has shown significant speed-ups by combining bidirectional indices and employing variations of <i>search schemes</i>. Search schemes partition a query and describe how to search the resulting parts with a given error bound. The performance of search schemes can be approximated by the <i>node count</i>, which represents an upper bound of the number of search steps. Finding <i>optimum search schemes</i> is a difficult combinatorial optimization problem that becomes hard to solve for four and more errors. This paper improves on a few topics important to search scheme based searches: First, we show how search schemes can be used to model previously published approximate search strategies such as suffix filters, 01*0-seeds, or the pigeonhole principle. This unifies these strategies in the search scheme framework, makes them easily comparable and results in novel search schemes that allow for any number of errors. Second, we present a search scheme construction heuristic, which is on par with optimum search schemes and has a better node count than any known search scheme for equal or above four errors. Finally, using the different search schemes, we show that the node count measure is not an ideal performance metric and therefore propose an improved performance metric called the <i>weighted node count</i>, which approximates a search algorithm's run time much more accurately.</p>","PeriodicalId":33994,"journal":{"name":"NAR Genomics and Bioinformatics","volume":"7 1","pages":"lqaf025"},"PeriodicalIF":4.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11915513/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143658930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike protein structure prediction, RNA structure prediction remains a significant challenge in bioinformatics, primarily due to the scarcity of annotated RNA structure data and its varying quality.

In this work, we present NucleoSeeker, a tool designed to curate high-quality, tailored datasets from the Protein Data Bank (PDB) database. It is a unified framework that combines multiple tools and streamlines an otherwise complicated process of data curation. It offers multiple filters at structure, sequence, and annotation levels, giving researchers full control over data curation. Further, we present several use cases. In particular, we demonstrate how NucleoSeeker allows the creation of a nonredundant RNA structure dataset to assess AlphaFold3's performance for RNA structure prediction. This demonstrates NucleoSeeker's effectiveness in curating valuable nonredundant tailored datasets to both train novel and judge existing methods.

Here, we introduce a novel approach for SNP grouping, leveraging the determinant of linkage disequilibrium (LD) matrices as a comprehensive metric of multicollinearity. This method builds on the established use of determinants in regression analysis as an aggregate measure of variable interdependence. We proposed that SNPs be grouped by evaluating the determinant of their LD matrices, with the approach validated using both synthetic genotype-phenotype data and real-world data from genome-wide association studies (GWAS) of ischemic stroke. Application of this method identified two previously known and five novel candidate genes associated with the onset of disease. Additionally, we developed a straightforward procedure to estimate a critical parameter for the model: the minimal determinant value for an LD matrix to be considered singular. In summary, the determinant of the LD matrix serves as a robust integrative measure for assessing SNP group quality. This metric underpins a bioinformatics workflow capable of identifying genomic loci associated with disease onset, offering a valuable tool for advancing genetic association studies.</p>","PeriodicalId":33994,"journal":{"name":"NAR Genomics and Bioinformatics","volume":"7 1","pages":"lqaf024"},"PeriodicalIF":4.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11915498/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143658839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative analyses with established methods such as flowPeaks, dpcp, and ddPCRclust reveal that Polytect often surpasses established methods, both on empirical and simulated data. Polytect manages to merge excess clusters, while also successfully identifying empty clusters when fewer than the maximally observable number of clusters are present.
