Extract the dimensional reductions of a Seurat object as a compact payload

Returns one entry per dimensional reduction of object (except those named in exclude) with the cell embeddings, the reduction key and its assay, so that a forked annotation run can hand a case's projections back without keeping the whole object alive.

Usage

SeuratProjectionPayload(object, exclude = NULL)

Arguments

object

Seurat object

exclude

Names of reductions to skip

Value

A list with one entry per reduction: name, embeddings (matrix, cells x dims), key, assay.
