Abstract Spatially resolved omics technologies are transforming our understanding of biological tissues. However, the handling uni- and multimodal spatial datasets remains a challenge owing to large data volumes, heterogeneity types lack flexible, spatially aware structures. Here we introduce SpatialData, framework that establishes unified extensible multiplatform file-format, lazy representation larger-than-memory data, transformations alignment common coordinate systems. SpatialData facilitates annotations cross-modal aggregation analysis, utility which is illustrated in context multiple vignettes, including integrative analysis on Xenium Visium breast cancer study.

Abstract Spatially resolved transcriptomics (SRT) is a pioneering method for simultaneously studying morphological contexts and gene expression at single-cell precision. Data emerging from SRT are multifaceted, presenting researchers with intricate matrices, precise spatial details comprehensive histology visuals. Such rich datasets, unfortunately, render many conventional methods like traditional machine learning statistical models ineffective. The unique challenges posed by the specialized nature of data have led scientific community to explore more sophisticated analytical avenues. Recent trends indicate an increasing reliance on deep algorithms, especially in areas such as clustering, identification spatially variable genes alignment tasks. In this manuscript, we provide rigorous critique these advanced methodologies, probing into their merits, limitations avenues further refinement. Our in-depth analysis underscores that while recent innovations tailored been promising, there remains substantial potential enhancement. A crucial area demands attention development can incorporate biological nuances, phylogeny-aware processing or minuscule image segments. Furthermore, addressing elimination batch effects, perfecting normalization techniques countering overdispersion zero inflation patterns seen pivotal. To support broader endeavors, meticulously assembled directory readily accessible databases, hoping serve foundation future research initiatives.

Technical limitations in spatial and single-cell omics sequencing pose challenges for capturing describing multimodal information at the scale. To address this, we develop SIMO, a computational method designed Spatial Integration of Multi-Omics datasets through probabilistic alignment. Unlike previous tools, SIMO not only integrates transcriptomics with RNA-seq but expands beyond, enabling integration across multiple modalities, such as chromatin accessibility DNA methylation, which have been co-profiled spatially before. We benchmark on simulated datasets, demonstrating its high accuracy robustness. Further application biological reveals SIMO's ability to detect topological patterns cells their regulatory modes layers. Through comprehensive analysis real-world data, uncovers heterogeneity, offering deeper insights into organization regulation molecules. These findings position powerful tool advancing biology by revealing previously inaccessible insights.
