Webz_scores Only applies if the number of permutations is greater than 1. A logical value. TRUE: the z-scores will be returned for the pathway activity estimations. FALSE: the function returns a normalized z-score value between -1 and 1. get_nulldist Only applies if the number of permutations is greater than 1. A logical value. WebComplex Integration Tasks. In the section above, we’ve presented the Seurat integration workflow, which uses canonical correlation analysis (CCA) and multiple nearest neighbors (MNN) to find “anchors” and integrate across samples, conditions, modalities, etc. While the Seurat integration approach is widely used and several benchmarking studies support its …
WebSeurat calculates highly variable genes and focuses on these for downstream analysis. FindVariableGenes calculates the average expression and dispersion for each gene, places these genes into bins, and then calculates a z-score for dispersion within each bin. This helps control for the relationship between variability and average expression.
