This can happen occasionally. The min.width argument specifies the minimum
number of probes in the minor arc of the circular (remember this is circular
binary segmentation). So if you can get 2 probes from one end and 3 from
the other to be significantly different the middle you will get a

Hi Lavinia:
Unlike the 500k array, Affy 6.0 (and 5.0) are single chips. Different
aliquots of DNA are processed by StyI and NspI separately and mixed together
and hybed to a single chip. There are reasons why my collaborator wants to
use NspI only.
