downsample_counts(adata, counts_per_cell=None, total_counts=None, random_state=0, replace=False, copy=False)¶
Downsample counts from count matrix.
counts_per_cellis specified, each cell will downsampled. If
total_countsis specified, expression matrix will be downsampled to contain at most
- 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_countsit will be downsampled to have this number.
- random_state :
Random seed for subsampling.
- replace :
Whether to sample the counts with replacement.
- copy :
AnnDatais passed, determines whether a copy is returned.
- adata :
- Return type
copyreturns or updates an
