Dear Nianhua & list, to continue the discussion on the hyperGTest and ath1121501 (https://stat.ethz.ch/pipermail/bioconductor/2006-October/014715.html) . As far as I understood, this function needs the ENTREZID variable of the studied environment, which in this case doesn't exist (~because we work with the AGI-IDs and not the entrezIDs): > hgOver <- hyperGTest(params) Error in get(x, envir, mode, inherits) : variable "ath1121501ENTREZID" of mode "environment" was not found Did I completely miss it and is there a way around this problem or should I look for another function, like Thomas Girke's GOHyperGAll? Many thanks in advance, Tine

Dear Tine, Could you please run traceback() and sessionInfo() after the error and send me the results? Many thanks. Those will be helpful in debugging. It will be even better if you happen to have a small example script. thanks nianhua

Hi Nianhua, after updating several packages (ath121501, GO,.. ) it worked fine. I am still wondering about the following: the variable ath1121501ENTREZID is not defined in the ath1121501 environment, right? Is in this case (for this arabidopsis-specific environment only) ath1121501ENTREZID identical to ath1121501ACCNUM? I have build my own cdf and annotation package for this array, is the following correct: > Myath1annotENTREZID <- Myath1annotACCNUM in order to being able to use hyperGTest? thanks!

Yes if your annotation package was built by athPkgBuilder. best nianhua
