[BioC] Error message after mass5calls command MAS5.0 absolute detection

[cstrato]

Dear Amit,

As Jim did already mention, mas5calls do work only for arrays containing 
PM/MM-oligos. For PM-only arrays Affymetrix has developed an alternative 
to mas5calls, which is called DABG calls.

As Jim kindly said, package xps has implemented function dabg.call() for 
PM-only arrays. However, function mas5.call() is implemented in xps in a 
way that does also work for PM-only arrays, although I would recommend 
to use dabg.call().

Best regards,
Christian
