Before anything else, have you considered the low-level API to TumorBoost?

  http://aroma-project.org/vignettes/tumorboost-lowlevel

That operates on basic R data types such as vectors and matrices.

If you're considering doing parent-specific segmentation, you may also
be interested in Paired PSCBS (which does TumorBoost for you).  Have a
a look at the 'Paired PSCBS' vignette;

  http://cran.r-project.org/web/packages/PSCBS/

If you're still interested in aroma-level API to TumorBoost, i.e.
TumorBoostNormalization, it is possible to create your own *.asb
binary data files containing TCN and BAF.  You'll then also need to be
able to setup UGP annotation data files (for genomic positions).  (The
*.acf genotype file can be obtained on the fly).  However, if you
don't really need this, I recommend to hold back on this one, because
in the future there may be easier ways to do this.

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.
