hgug4100aUNIGENE {hgug4100a} | R Documentation |
hgug4100aUNIGENE is an R environment that provides mappings between manufacturer identifiers and UniGene identifiers.
Each manufacturer identifier is mapped to a UniGene identifier. An NA
is
reported if the manufacturer identifier cannot be mapped to UniGene at this time.
A UniGene identifier represents a cluster of sequences of a gene. Using UniGene identifiers one can query the UniGene database for information about the sequences or the Entrez Gene database for information about the genes.
Mappings were based on data provided by:
Entrez Gene:ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Fri Aug 24 19:42:04 2007
