[BioC] Using read.maimages() with Imagene output files.

[Gordon Smyth]

Hi Nick,

You're closer to me, both geographically and time-zone wise, than Luke is 
so could you please send me four imagene files, i.e., both channels for two 
different arrays. Please zip or otherwise compress the files and then email 
them to me in four separate emails.

Also, does your scanner produce a separate gene allocation list specifying 
which gene corresponds to which spot? At the moment, limma provides direct 
support only for Genepix allocation lists.

Cheers
Gordon
