Findvariablefeatures mvp
WebUse this function as an alternative to the NormalizeData, FindVariableFeatures, ScaleData workflow. Results are saved in a new assay (named SCT by default) with counts being (corrected) counts, data being log1p (counts), scale.data being pearson residuals; sctransform::vst intermediate results are saved in misc slot of new assay. Usage WebJul 16, 2024 · These methods aim to identify shared cell states that are present across different datasets, even if they were collected from different individuals, experimental conditions, technologies, or even species. Our method aims to first identify ‘anchors’ between pairs of datasets.
