     gahgu95eSYMBOL is an R environment that provides mappings between
     custom probeset identifiers and gene abbreviations.

_D_e_t_a_i_l_s:

     Each identifier is mapped to an abbreviation for the corresponding
     gene. An 'NA' is reported if there is no known abbreviation for a
     given gene.

     Symbols typically consist of 3 letters that define either a single
     gene (ABC) or multiple genes (ABC1, ABC2, ABC3). Gene symbols can
     be used as key words to query public databases such as Entrez
     Gene.

     Mappings were based on data provided by:
