Signature scores were computed using the Seurat function “AddModuleScore” using the gene signature of interest. This function calculates for each individual cell the average expression of each gene signature, subtracted by the aggregated expression of control gene sets (Tirosh et al., 2016). All analyzed genes are binned into 25 bins based on averaged expression, and for each gene of the gene signature, 100 control genes are randomly selected from the same bin as the gene. Seurat has several tests for differential expression which can be set with the test.use parameter (see our DE vignette for details). For example, the ROC test returns the ‘classification power’ for any individual marker (ranging from 0 - random, to 1 - perfect).
The 350 GO pathway gene lists, publicly available (GO Consortium; containing the phrase ‘SIGNALING_PATHWAY’ in the ‘Biological Process’ category), were used to compute pathway scores for each cell type using the AddModuleScore function in Seurat.

8.4.1 Creating a seurat object. To analyze our single cell data we will use a seurat object. Can you create an Seurat object with the 10x data and save it in an object called 'seurat'? hint: CreateSeuratObject(). Can you include only genes that are are expressed in 3 or more cells and cells with complexity of 350 genes or more?

To predict sampling time-biased cells, we used the AddModuleScore function of Seurat to compute a time score per cell using a signature calculated on the male donor (training set). We then fitted a logistic regression model using the time score as explanatory variable. Subsequently, we predicted the probability of being "biased" for every ...
