  Gets the indices of probepairs with the same pair of SNP nucleotides.
  Note that the order of allele A and allele B is irrelevant.
  For instance, all probepairs with nucleotides (A,T) are calibrated
  together with all probepairs with nucleotides (T,A) reversed.

A cross-platform R framework that facilitates processing of any number of Affymetrix microarray samples regardless of computer system.  The only parameter that limits the number of chips that can be processed is the amount of available disk space.  The Aroma Framework has successfully been used in studies to process tens of thousands of arrays.  This package has actively been used since 2006.
