Hi,

I am approaching beadarray for the first time and I have a query about the bead-level data that I have received.  From what I read four columns are expected in the .txt files (Code, Grn, GnrX, GnrY).  I want to clarify that the column GrnB (as per Dunning, 2011) can only be arise from analysis of .tif files, and that 'readIllumina' will extract background corrected intensities from the .txt files.  As yet the .tif files have not been made available to me.

Many thanks in advance

Alan
