Hello everyone This is my first message to Bioconductor, I hope someone out there can help me.?I have been working through the goseq vignette and adapting it to my own dataset. ?I have got my list of enriched go categories, which looks like this: > head(GO.wall) ? ? ? ? category over_represented_pvalue under_represented_pvalue 3217 GO:0006954 ? ? ? ? ? ?1.496746e-10 ? ? ? ? ? ? ? ? ? ? ? ?1 3548 GO:0008009 ? ? ? ? ? ?4.502492e-10 ? ? ? ? ? ? ? ? ? ? ? ?1 9081 GO:0042379 ? ? ? ? ? ?1.010877e-09 ? ? ? ? ? ? ? ? ? ? ? ?1 2160 GO:0005126 ? ? ? ? ? ?1.033292e-09 ? ? ? ? ? ? ? ? ? ? ? ?1 2159 GO:0005125 ? ? ? ? ? ?1.534272e-09 ? ? ? ? ? ? ? ? ? ? ? ?1 4251 GO:0009611 ? ? ? ? ? ?1.983311e-09 ? ? ? ? ? ? ? ? ? ? ? ?1 I can get a list of the genes which are contained in each GO category using : >?ensembl.gene.ids=get("GO:0006954", org.Hs.egGO2ALLEGS) > unlist(mget(unique(ensembl.gene.ids), org.Hs.egGENENAME)) but this just gives me a list of ALL the genes attached to this GO category. ?I?would like to find out which of my DE genes are in this GO category. I have referred to a previous Bioconductor post <https: stat.ethz.ch="" pipermail="" bioconductor="" attachments="" 20110308="" 92b2="" 7df4="" attachment.pl=""> which shows how to get a list of all the genes in each GO category, like this: > data(genes) > genes2go=getgo(names(genes),'hg19','ensGene') > go2genes=goseq:::reversemapping(genes2go) Here is an extract from go2genes: > go2genes$'GO:0006954' ?

Hi Helen Here's how I did exactly what you want (with added symbol and logFC goodness) I was studying cows hence the bosTau4 and using ENSEBML gene ids so hence the ensGene. You can adapt this all you like though. These are the libraries I loaded upfront (i.e. before the edgeR analysis from which the following is snipped): library(edgeR) library(org.Bt.eg.db)#cows! library(goseq) library(GO.db) library(annotate) #this calculates a vector that indicates whether each gene is regulated (at FDR 1% in my case) or not. It's fed to the nullp function of goseq (see below) # e.g. 0 0 1 1 0 0 1 # two genes not regulated, next two are, next two not etc genes <- as.integer(p.adjust(lrtFiltered$table$p.value, method = "BH") < 0.01)#FDR = 1% #...GO ANALYSIS...# pwf=nullp(genes,'bosTau4','ensGene') # genes = the regulated genes goCats <- goseq(pwf, 'bosTau4','ensGene', test.cats=("GO:BP")) sigCats <- goCats[which(goCats[,2] < 0.05),] # getting the sig categories #let's annotate the GO categories cats <- sigCats$category terms <- stack(lapply(mget(cats, GOTERM, ifnotfound=NA), Term)) #write out GO data sigCats$Term <- with(sigCats, terms$values[match(terms$ind, sigCats$category)] ) #get the genes in each category allGos <- stack(getgo(rownames(topGenes$table), 'bosTau4', 'ensGene')) # so here I pull the GO terms for every gene that is regulated. #add the terms onlySigCats <- allGos[allGos$values %in% sigCats$category,] onlySigCats$Term <- with( onlySigCats, terms$value[match(onlySigCats$values, terms$ind)] ) #add the gene symbol onlySigCats$Symbol <- with( onlySigCats, annot2[,2][match(onlySigCats$ind, rownames(annot2) )] ) #add the gene logFC onlySigCats$logFC <- with( onlySigCats, topGenes$table$logFC[match(onlySigCats$ind, rownames(topGenes$table) )] ) You can then write out this table.

Hi Ian and Helen - I tried this bit of code but got an error at the point of 

> terms <- stack(lapply(mget(cats, GOTERM, ifnotfound=NA), Term))
Error in stack(lapply(mget(cats, GOTERM, ifnotfound = NA), Term)) : 
  error in evaluating the argument 'x' in selecting a method for function 'stack': Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘Term’ for signature ‘"logical"’

am I missing something, or not put the code in correctly>

preceeding the offeding line, this is how I set it up

KEGG.Sig.PC3.40.samp <- goseq(pwf.KG, "hg19", "knownGene", method="Sampling",repcnt=1000, test.cats = c("KEGG"))

goCats <- KEGG.Sig.PC3.40.samp
sigCats <- goCats[which(goCats[,2]<0.05),]

cats <- sigCats$category

Is it a KEGG thing (does this only work with GO terms)?

Cheers,

Matt

Hi Iain Gallagher ,

I tried using your code to extract the genes of my interest that are DE from the list of DElist given to goseq analysis. But i got the following error. Could you please tell me what was the mistake that is being done. 

#Goseq analysis
genes=as.integer(p.adjust(de.cmn$table$PValue[de.cmn$table$logFC!=0],method="BH")<.05)

names(genes)=row.names(de.cmn$table[de.cmn$table$logFC!=0,])
table(genes)

pwf=nullp(genes,"hg19","knownGene")

GO.wall=goseq(pwf,"hg19","knownGene")

enriched=GO.wall$category[p.adjust(GO.wall$over_represented_pvalue, method="BH")<.05]

biocLite("org.Hs.eg.db")
library(org.Hs.eg.db)
biocLite("GO.db")
library(GO.db)
biocLite("annotate")
library(annotate)
sigCats <- GO.wall[which(GO.wall[,2] < 0.05),]
cats <- sigCats$category
terms <- stack(lapply(mget(cats, GO:0005615, ifnotfound=NA), extracellular space))

ERROR: Error: unexpected symbol in "terms <- stack(lapply(mget(cats, GO:0005615, ifnotfound=NA), extracellular space"

Can you try this! Change this line: 

terms <- stack(lapply(mget(cats, GO:0005615, ifnotfound=NA), extracellular space))

To this: 

terms <- stack(lapply(mget(cats, "GO:0005615", ifnotfound=NA), extracellular space))
