Description:

Package for parsing Affymetrix files (CDF, CEL, CHP, BPMAP, BAR).
It provides methods for fast and memory efficient parsing of
Affymetrix files using the Affymetrix' Fusion SDK. Both ASCII- and
binary-based files are supported. Currently, there are methods for
reading chip definition file (CDF) and a cell intensity file (CEL).
These files can be read either in full or in part. For example,
probe signals from a few probesets can be extracted very quickly
from a set of CEL files into a convenient list structure.
