anndata.AnnData.raw

property AnnData.raw: Raw

Store raw version of X and var as .raw.X and .raw.var.

The raw attribute is initialized with the current content of an object by setting:

adata.raw = adata.copy()

Its content can be deleted:

adata.raw = None
# or
del adata.raw

Upon slicing an AnnData object along the obs (row) axis, raw is also sliced. Slicing an AnnData object along the vars (columns) axis leaves raw unaffected. Note that you can call:

adata.raw[:, 'orig_variable_name'].X

to retrieve the data associated with a variable that might have been filtered out or “compressed away” in X.
