     gahgu95dALIAS is an R object that provides mappings between common
     gene symbol identifiers and probeset identifiers.

_D_e_t_a_i_l_s:

     Each gene symbol is mapped to a vector of probeset identifiers.
     The vector contains all probeset identifiers that are found for
     that symbol. An 'NA' is reported for any gene symbol that  cannot
     be mapped to any probeset identifiers.

     This mapping includes ALL gene symbols including those which are
     already listed  in the SYMBOL map.  The SYMBOL map is meant to
     only list official gene symbols,  while the ALIAS maps are meant
     to store all used symbols.

     Mappings were based on data provided by: Genecards (
     http://www.genecards.org ) on 2009-mag06
