episcanpy.pp.downsample_counts(adata, counts_per_cell=None, total_counts=None, random_state=0, replace=False, copy=False)¶ Downsample counts from count matrix.
If counts_per_cell is specified, each cell will downsampled. If total_counts is specified, expression matrix will be downsampled to contain at most total_counts.
- Parameters
- adata
Annotated data matrix.
- counts_per_cell
Target total counts per cell. If a cell has more than ‘counts_per_cell’, it will be downsampled to this number. Resulting counts can be specified on a per cell basis by passing an array.Should be an integer or integer ndarray with same length as number of obs.
- total_counts
Target total counts. If the count matrix has more than total_counts it will be downsampled to have this number.
- random_state
Random seed for subsampling.
- replace
Whether to sample the counts with replacement.
- copy
If an
AnnDatais passed, determines whether a copy is returned.
- Returns
Depending on copy returns or updates an adata with downsampled .X.
