Hello, I don't know very well the bioconductor packages, but I try to use some of them to analyse some data. More precisely, I try to use the function GOHyperg from package GOstats for Arabidopsis data. For the function GOhyperG, there is an example with the hgu95av2 package (human genome) and I would like to apply this example with the package ath1121501 (Arabidopsis package). But the function GOhyperG() uses a field called LOCUSID in the package hgu95av2. This field does not exist in the ath1121501 package...So, the function GOhyperG could not be applied to analyze arabidopsis data... So, could anyone indicate me how to find a solution? Thanks for your help. Olivier.

We are planning to make this easier, and hope to have something in the next release. For now, the workaround that Nianhua came up with should get you going. + seth

One of the best resources we have is the mailing list, which can be searched using gmane (link on BioC website under 'Join Mailing List'). This same question was asked about six days ago, and Nianhua Li was kind enough to give a very detailed answer that can be found here: http://article.gmane.org/gmane.science.biology.informatics.conductor/9 737/match=nianhua+gohyperg See her response under question #3.
