text: user5098: I have barcodes.tsv, genes.tsv and matrix.mtx file from my RNA seq data and I want to generate a scRNA counts files using R. When I tried using the readMM function, it gave me the following error: 
  Error: cannot allocate vector of size 185.1 Gb. 
  
  This happens even when I run it as a job. How can I generate a combined csv file using R?
  Thank you.
  
  user6232: I use the DropletUtils package from Bioconductor. Getting counts begins like this:
  library(DropletUtils)
  filePath <- "path_to_data/raw_feature_bc_matrix/"
  singleCellExperiment <- read10xCounts(filePath, col.names = TRUE)
