)Directory containing the files.
The file suffix of the individual files. Must be the same across all files being imported. This is used to detect files to import and their GEO IDs.
logical. Whether gene IDs are present in first column or in row names of delimited file. If TRUE will move the first column to row names before creating final matrix. Default is TRUE.
a vector of samples within directory to read in (can be either with or
without file_suffix see full_names). If NULL will read in all subdirectories.
logical (default FALSE). Whether or not the sample_list vector includes the file suffix.
If FALSE the function will add suffix based on file_suffix parameter.
a set of sample names to use for each sample entry in returned list.
If NULL will set names to the directory name of each sample.
Is the barcode suffix a period and should it be changed to "-". Default (FALSE; barcodes will be left identical to their format in input files.). If TRUE "." in barcode suffix will be changed to "-".
logical (default FALSE). Whether to use multiple cores when reading in data. Only possible on Linux based systems.
if parallel = TRUE indicates the number of cores to use for multicore processing.
logical (default FALSE) whether or not to merge samples into a single matrix or return
list of matrices. If TRUE each sample entry in list will have cell barcode prefix added. The prefix
will be taken from sample_names.
List of gene x cell matrices in list format named by sample name.
