Hai all,

I have been using Agi4x44 preprocess annotation package for the analysis of
8x60k mRNA data analysis and it was found to be wrong. Now I am using the
new annotation package* "HsAgilentDesign026652.db"* for analysing Agilent
8x60k chip, which uses additional packages along with the
Agi4x44PreProcess annotation package.
I hope this will work out for my 8x60k chip analysis.

Now am facing a problem in this step while doing the analysis:

    *  CV.rep.probes(dd,"HsAgilentDesign026652.db",foreground="MeanSignal",
raw.data=TRUE,writeR=FALSE, targets)*
*
*
While running in 'R' its showing a result like:

*Error in mget(x, envir = getAnnMap(what, chip = data, load = load),
ifnotfound = NA) : *
*  second argument must be an environment*

Could any one please help in sorting out this problem?

Thanks in advance,

Murali
