Hello everyone!

Is there a way to calculate the summed expression of a group of genes in R? I know about the function AggregateExpression in Seurat but it does not take the list of genes in features argument.

Thanks!

What have you already tried? What is the structure of your gene expression object? These details help us to make appropriate suggestions.

if you have a matrix of gene counts where the row names are genes and columns are samples, you can try the following:

# vector of genes of interest
genes <- c("Gene1", "Gene2", "Gene3")

# get vector of aggregated gene expression for each column in my gene count matrix
aggregated <- apply(gene_counts[genes,], 2, sum)
