Hi, I've been trying to use the hyperGTest method from the GOstats package with some yeast ORF data. I notice in this thread from a month or so ago that there are problems at the moment with using any of the yeast annotation sets apart from 'YEAST' (which is deprecated) due to missing ID2EntrezID methods: https://stat.ethz.ch/pipermail/bioconductor/2008-June/022697.html I just wanted to make sure that this was still the case and I guess fish around for an estimated ETA for when the org.Sc.sgd.db annotations (which are replacing YEAST as I understand it) will be compatible with hyperGTest? Also, is the exact source of GO annotations used in these packages documented anywhere? Looking in the DESCRIPTION file I see 'primarily based on mapping using ORF identifiers from SGD' for org.Sc.sgd.db and 'assembled using data from public data repositories' for YEAST. Should I just take it these are based on the SGD GO annotation file from the date given in the Packaged field of the DESCRIPTION file? For YEAST there is also a Created field which is aprox. 1 month prior to the Packaged date so I'm guessing the real age of the data is that one? The yeast annotations change so quickly it's useful to be able to pin this down as accurately as possible. Thanks in advance for any help with these questions.

Hi Alex, If you are willing to use R-devel and Bioc-devel, the issue should be fixed there. I would be interested in hearing of any problems you might have (or successes) using that version. I am waiting for some reports of success before I port this to release, best wishes Robert Alex Gutteridge wrote: > Hi, > > I've been trying to use the hyperGTest method from the GOstats package > with some yeast ORF data.

For YEAST there is the man page is pretty explicit, (?org.Sc.sgdGO) Mappings were based on data provided by: Yeast Genome ( ftp://genome-ftp.stanford.edu/pub/yeast/data_download ) on 2008-Mar29 I am not sure what more we could put there. best wishes Robert > also a Created field which is aprox. 1 month prior to the Packaged date > so I'm guessing the real age of the data is that one?

Hi, Just to confirm the org.Sc.sgd.db package and GOstats seem to work fine together for me in Bioc-devel (Sample session pasted below).

Hi Alex, You can see the sources used to make the org.Sc.eg.db package by calling its dbInfo() function like this: org.Sc.sgd_dbInfo() You can see that there are 3 sources of information listed for this package. To make the GO to yeast mappings, the mappings themselves come from SGD as listed in the help pages.

Hi Alex, afraid I cannot your questions about the yeast annotation package, but I would like to mention that alternatively you could create a simple list mapping gene identifiers to GO identifiers using the biomaRt package to query the up-to-date annotation in the Ensembl data base and use this list to do the same analysis using the topGO package. The topGO package has a slightly different interface to set up the test, but the vignette provides a good working example. Hope this helps.
