mgrhomologyLL2HGID {mgrhomology} | R Documentation |
R environments that provides mappings between public database identifiers and internal HomoloGeneIDs (HGID) used by NCBI to represent sequences for Magnaporthe grisea. Public database identifiers include Entrez Gene identifiers (LL) and GenBank Accesion/RefSeq numbers (ACC).
Each R environment provides mapping between either HomoloGeneIds and database identifiers. or the converse. The mapping direction is indicated by the name of the environment. For instance, mgrhomologyACC2HGID provides mappings between GenBank accession numbers and HomoloGeneIds.
For each environment, a given identifier will map to a named vector of identifiers. the names of which are the NCBI code for that organism.
Mappings contained were based on data provided by HomoloGene.
