merge_adata
Combine multiple AnnData objects along specified axes (observations or variables) using customizable alignment and merging strategies. Supports inner and outer joins, index uniqueness, and batch labeling for enhanced single-cell RNA sequencing data integration.
Instructions
merge multiple adata
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| axis | No | Which axis to concatenate along. 'obs' or 0 for observations, 'var' or 1 for variables. | obs |
| fill_value | No | When join='outer', this is the value that will be used to fill the introduced indices. | |
| index_unique | No | Whether to make the index unique by using the keys. If provided, this is the delimiter between '{orig_idx}{index_unique}{key}'. | |
| join | No | How to align values when concatenating. If 'outer', the union of the other axis is taken. If 'inner', the intersection. | inner |
| keys | No | Names for each object being added. These values are used for column values for label or appended to the index if index_unique is not None. | |
| label | No | label different adata, Column in axis annotation (i.e. .obs or .var) to place batch information in. | |
| merge | No | How elements not aligned to the axis being concatenated along are selected. | |
| pairwise | No | Whether pairwise elements along the concatenated dimension should be included. | |
| uns_merge | No | How the elements of .uns are selected. Uses the same set of strategies as the merge argument, except applied recursively. |
