translateTargetId: Translate a protein target identifier to another identifier...

In bioassayR: Cross-target analysis of small molecule bioactivity

Description

Returns a character vector of the protein target identifiers using the specified category (classification system). This is most often used to translate NCBI Protein GI numbers (as provided with the pre-build PubChem Bioassay database) into UniProt identifiers.

Usage

translateTargetId(database, target, category, fromCategory = "GI")

Arguments

database	A BioassayDB database to query.
target	A protein target identifier to query (as set by the category option, with a default of "GI").
category	The specified identifier type to return, such as 'UniProt'.
fromCategory	The identifier type of the query (default "GI").

Value

A character vector of the protein target identifiers of the category specified for the target specified. An NA is returned if no matching values exist in the database.

Examples

## create sample database
myDatabaseFilename <- tempfile()
mydb <- newBioassayDB(myDatabaseFilename, indexed=FALSE)

## load a sample translation from GI 6686268 to UniProt P11712
loadIdMapping(mydb, "6686268", "UniProt", "P11712")

## get UniProt identifier(s) for GI Number 6686268
UniProtIds <- translateTargetId(mydb, "6686268", "UniProt")
UniProtIds

## get GI identifier(s) for UniProt ID P11712
GIs <- translateTargetId(mydb, "P11712", "GI", "UniProt")
GIs

## disconnect from and delete sample database
disconnectBioassayDB(mydb)
unlink(myDatabaseFilename)
