Yes, nothing in the TumorBoost method makes use of genomic locations
(nor chromosome or position); it normalizes tumor BAFs given the
corresponding matched normal BAFs for SNPs independently of each
other.

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.
