Seurat (version 2.3.4)

TransferIdent: Transfer identity class information (or meta data) from one object to another

Description

Transfers identity class information (or meta data) from one object to another, assuming the same cell barcode names are in each. Can be very useful if you have multiple Seurat objects that share a subset of underlying data.

Usage

TransferIdent(object.from, object.to, data.to.transfer = "ident",
  keep.existing = TRUE, add.cell.id1 = NULL)

Arguments

object.from

Seurat object to transfer information from

object.to

Seurat object to transfer information onto

data.to.transfer

What data should be transferred over? Default is the identity class ("ident"), but can also include any column in [e-mail]

keep.existing

For cells in object.to that are not present in object.from, keep existing data? TRUE by default. If FALSE, set to NA.

add.cell.id1

Prefix to add (followed by an underscore) to cells in object.from. NULL by default, in which case no prefix is added.

Value

A Seurat object where object@ident or [e-mail] has been appropriately modified

Examples

# NOT RUN {
# Duplicate the test object and assign random new idents to transfer
pbmc_small@ident
pbmc_small2 <- SetIdent(object = pbmc_small, cells.use = [e-mail],
 ident.use = sample(pbmc_small@ident))
pbmc_small2@ident
pbmc_small <- TransferIdent(object.from = pbmc_small2, object.to = pbmc_small)
pbmc_small@ident

# }
