WebApr 12, 2024 · Seurat提供了两种工作流程来识别与组织内空间位置相关的分子特征。 第一种是根据组织内预注释的解剖区域进行差异表达，这可能是由无监督聚类或先验知识决定的。 这种策略在这种情况下是有效的，因为上面的集群表现出明显的空间限制。 de_markers <- FindMarkers (Brain, ident.1 = 5, ident.2 = 6)SpatialFeaturePlot (object = Brain, features = … WebJul 22, 2024 · You can always pad your TPM matrix with NaN and add it to the Seurat object as an assay, if that is what you want. Alternatively, you could filter the Seurat object to keep only the rows present in the TPM matrix and re-run. Below is an example padding the missing data in the TPM matrix with NaN, as well as the alternative subsetting method:
Seurat: Integration and Label Transfer – NGS Analysis
For typical scRNA-seq experiments, a Seurat object will have a single Assay ("RNA"). This assay will also store multiple 'transformations' of the data, including raw counts (@counts slot), normalized data (@data slot), and scaled data for dimensional reduction (@scale.data slot). See more Summary information about Assay objects can be had quickly and easily using standard R functions. Object shape/dimensions can be found using the dim, ncol, … See more Accessing data from an Assay object is done in several ways. Expression data is accessed with the GetAssayData function. Pulling expression data from the data … See more Methods for the Assayclass can be found with the following: 1. [: access expression data from the dataslot 2. [[: access feature-level metadata 3. [[<-: add … See more WebThe input for this analysis is a seurat object. We will use the one that we created in the QC lesson called filtered_seurat. # Normalize the counts seurat_phase <- NormalizeData(filtered_seurat) Next, we take this normalized data and check to see if data correction methods are necessary.
