Initializes the cisTopic object from CellRanger ATAC output files and defined regions.
createcisTopicObjectFrom10X(
fragments,
regions,
metrics,
project.name = "cisTopicProject",
min.cells = 1,
min.regions = 1,
is.acc = 1,
keepCountsMatrix = TRUE,
...
)
fragments |
Fragment file from CellRanger ATAC (/outs/fragments.tsv.gz) |
regions |
Path to the bed file with the defined regions. |
metrics |
List of CellRanger barcodes and their metrics (/outs/singlecell.csv) |
project.name |
Project name (string). |
min.cells |
Minimal number of cells in which the region has to be accessible. By default, all regions accessible in at least one cell are kept. |
min.regions |
Minimal number of regions that have to be accessible within a cell to be kept. By default, all cells with at least one region accessible are kept. |
is.acc |
Number of counts necessary to consider a region as accessible. |
keepCountsMatrix |
Whether to keep the counts matrix or not inside the object. For large matrices, we recommend to set this to FALSE. |
Returns a cisTopic object with the counts data stored in object@count.matrix. object@binary.count.matrix, object@cell.names, object@cell.data (including counting statistics), object@regions.ranges, object@regions.data are also initialized.
