For me "bin" means "binary".  If you use the low-level API there is no
need to create binary files; just read the Illumina BAF (and LRR) data
into memory in, say, a data frame and then pass those values to
normalizeTumorBoost().

When reporting problems on aroma.affymetrix, make sure 1) to run the latest 
version of the package, 2) to report the output of sessionInfo() and 
traceback(), and 3) to post a complete code example.
