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 * * * * [[alternative HTML version deleted]]
