I'm working with some large Seurat objects (MOCA, MCA, Tabula Muris) studying gene coexpression, and I'm running into memory issues.
Is it possible to remove all genes in a Seurat object that are not in a specified gene array? Ideally I'd like to be working with a small R matrix with say, 250k rows (cells) and 10-50 columns (gene expression data) which will enable fast processing and comprehensive analysis using other packages.
