If i is a vector with cell-level meta data names, a data frame (or vector of drop = TRUE) with cell Now, in RStudio, we should have all of the data necessary to create a Seurat Object: the matrix, a file with feature (gene) names, a file with cell barcodes, and an optional, But this file has fewer cells than the Seurat object I already have. colnames_from: Vector of names Get unique features from metadata column in seurat object. The counts table has one column per cell and the rows are features (genes). ShaktiprasadM opened this issue I'm thinking one way to do this is to add a metadata column to the Seurat object classifying the cells as +/- for the marker. Retrieves column names from an object's metadata that match a specified pattern. By default, it identifies positive and negative markers of a single cluster (specified in ident. By default, Seurat performs differential expression (DE) testing based on the non If return. census API. Specifically, I have per cell mean fluorescence intensity, xy locations, and phenotype.
