Conversion from a SingleCellExperiment object to a Seurat object can be done with as.SeuratI have tried to load data using different versions of the Seurat package (down to 4.0.3) to no avail. I am unfamiliar with Seurat but, provided it happens with multiple versions of Seurat, I think it might be related to changes in some of the dependency packages. EDIT just saw the other issue from Sep 23 #6420. I want to clarify that in our ...SummarizedExperiment implements the ‘matrix-like’ interface. This means that it supports the functions dim (), dimnames (), and two-dimensional [ -subsetting. Exercise Subset airway to contain the first 5 rows and first 4 columns. Check out the colData (), rowRanges (), and assay () of the resulting object. 2.3 Basic summaries of assay () valuesSummarizedExperiment 对象能够存储多个样本的观测值,同时存储用于描述观测值和样本的元数据(metadata)。 SummarizedExperiment 能够紧密结合样本,观测值与对应的metadata,比如,如果在分析中删除了某个样本,则可同步删除与这个样本相关metadata。 SummarizedExperiment 对象 SummarizedExperiment 对象本身是一个 gene x sample matrix ,这个 gene x sample matrix 储存在 assay中,同时在这个矩阵的基础上增加了对 gene 的注释信息 和 对 sample 的注释信息,也就是两个 metadata matrix。SingleCellExperiment is a class for storing single-cell experiment data, created by Davide Risso, Aaron Lun, and Keegan Korthauer, and is used by many Bioconductor analysis packages. Here we demonstrate converting the Seurat object produced in our 3k PBMC tutorial to SingleCellExperiment for use with Davis McCarthy’s scater package.In this vignette we demonstrate how to merge multiple Seurat objects containing single-cell chromatin data, by creating a new assay in each object containing a common set of peaks. To demonstrate, we will use four scATAC-seq PBMC datasets provided by 10x Genomics: 500-cell PBMC; 1k-cell PBMC; 5k-cell PBMC; 10k-cell PBMCIt creates an invisible layer that enables viewing the Bioconductor SummarizedExperiment object as a tidyverse tibble, and provides SummarizedExperiment-compatible dplyr, tidyr, ggplot and plotly functions. This allows users to get the best of both Bioconductor and tidyverse worlds.
