[BioC] backgroundCorrect offset value

[Prasad Siddavatam]

Hi Jim,

Thank you very much for you explanation. Now I can understand the reason. 

But when you said its up to the analyst to decide on the offset value.
Is this statement based on the number of genes I am 
expecting (to be differentially expressed) or on some other criteria.

Its is very critical because I am using several types of 
arrays (agilent, cDNAs)


Appreciate your help.
