     canine2ENTREZID is an R environment that provides mappings between
     manufacturer identifiers and Entrez Gene identifiers.

_D_e_t_a_i_l_s:

     Each manufacturer identifier is mapped to a vector of Entrez Gene
     identifiers. An 'NA' is assigned to those manufacturer identifiers
     that can not be mapped to an Entrez Gene identifier at this time.

     If a given manufacturer identifier can be mapped to different
     Entrez Gene identifiers from various sources, we attempt to select
     the common identifiers. If a concensus cannot be determined, we
     select the smallest identifier.

     Mappings were based on data provided by:

     Entrez Gene:\<URL: ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/>. Built:
     Source data downloaded from Entrez Gene on Thu Mar 15 18:25:45
