Load mtx formatted 10x or haircut matrices
read_matrix(path, cell_prefix = NULL, strip_10x_suffix = TRUE, use_gene_symbols = TRUE, split_matrix = FALSE, matrix_fn = "matrix.mtx.gz", features_fn = "features.tsv.gz", barcodes_fn = "barcodes.tsv.gz")
| path | path to directory with mtx matrix |
|---|---|
| cell_prefix | string to prefix to cell_id (default = NULL) |
| strip_10x_suffix | remove numeric suffix added by 10x e.g. change "TTTGTCAAGGTGTGGT-1" to "TTTGTCAAGGTGTGGT" (default = TRUE) |
| use_gene_symbols | If TRUE use gene symbols as row.names, if false then gene_ids will be used (default = TRUE) |
| split_matrix | Return a list of matrices split by feature types. Requires cellranger v.3 output. |
| matrix_fn | filename for matrix |
| features_fn | filename for genes file |
| barcodes_fn | filename for barcodes file |
