_Assay.copy

_Assay.copy(rows: Optional[numpy.ndarray] = None, cols: Optional[numpy.ndarray] = None) → missionbio.h5.data.assay.Assay

Create a duplicate of the assay.

If a subset of the rows and cols are chosen then this uses less memory than deepcopy since only a slice of the data is copied. Also, the metadata is modified if a sample is dropped while selecting the rows.

Args:

rows: Rows to copy. All rows copied by default. cols: Columns to copy. All Columns copied by default.

Returns:

Assay with selected rows and columns
