Hi, Sean

I've looked in the yeast2cdf package, all I see is functions
i2xy(i)      and
xy2i(x,y)
which convert x-y coordinates on the chip (1-496) to a single number index
(from 1 to 246016).

I am looking for affyIDs for each probe in the form  1780100_at1
1780100_at2 etc.
There should be 11 (or maybe 22) such affyIDs per probe set.

Any further help would be greatly appreciated.
Regards
Omri
