Welcome to the lumiRatIDMapping ID mapping Package. The purpose of this package is to provide ID mappings between different types of Illumina identifiers of Rat Expression chips and nuIDs, and also mappings from nuIDs to the the most recent Rattus norvegicus RefSeq release and Entez_Gene_ID. The library includes the data tables corresponding to all released Illumian Rat Expression chips before the package releasing date. Each table includes columns "Search_key" ("Search_Key"), "Target" ("ILMN_Gene"), "Accession", "Symbol", "ProbeId" ("Probe_Id") and "nuID". It also includes a nuID_MappingInfo table, which keeps the mapping information of nuID to Accession ID, Entrez_Gene_ID and Symbol. For the version after 1.8.0, all mapping information was based on Illumina manifest files. Information from new versions of manifest files will replace the old ones with the same probe id. The package is supposed to be used together with the Bioconductor lumi package.
We mapped nuIDs of Illumina Rat chips by BLASTing each probe sequence (converted from nuID) against the the most recent Rattus norvegicus RefSeq release. The mapping also includes the mapping quality information.
