Hi Guangchuang, I tried your ChIPseeker package to annotate some peaks. actually this worked pretty cool however when I tried to carry out Functional enrichment analysis on those peaks using ReactomePA I got some errors. here is the code I used:

files <- c('/GFP_peaks.bed', '/kd.bed')
print(files)

peak <- readPeakFile(files[[2]])
peak

covplot(peak, weightCol="V5")

peakAnno <- annotatePeak(files[[1]], tssRegion=c(-500, 500), 
                         TxDb=txdb, annoDb="org.Dm.eg.db")

til this step everything is working nicely. but the problem starts here: library(ReactomePA)

pathway1 <- enrichPathway(as.data.frame(peakAnno)$SYMBOL, organism = "fly")

I got the following:

No gene can be mapped....
--> return NULL...

which is not logic

could you please give advice to solve this problem?

Thanks Tamer

Instead of using SYMBOL, you should use entrez gene ID.

pathway1 <- enrichPathway(as.data.frame(peakAnno)$geneID, organism = "fly")

Hi Guangchuang, I am currently running RNA_seq pipeline and it was absolutely fine until I reached the KEGG step. first, I have 400 DE genes . I created matrix of ENTREZID and fold change. here is the head of my matrix:

> head(cp_matrix)
     35526      41092      39976      40831      36778      33636 
-0.4144379 -0.6321093 -0.3219794 -2.0373447  2.3645869  0.6998755

then I have run:

kegg_enrich <- enrichKEGG(gene = names(cp_matrix),
                          organism = "fly",
                          pvalueCutoff = 0.05, 
                          qvalueCutoff = 0.10)

and again I have the same error message:

No gene can be mapped....
--> return NULL...

any idea how to solve this

thanks much

Thanks much, one more question. how did you get these IDs????

thanks

From KEGG website. You should know these ID better than me as this is the species you are studying.

I am using ReactomePA and my input looks like this,entrezId & p-value :

I am getting following error after performing enrichPathway step:

> head(as.data.frame(x)) Error in as.data.frame.default(x) :  cannot coerce class "structure 
    ("enrichResult", package="DOSE")" to a > data.frame

I am not sure why is it so, can anyone explain me this? As far as I know DOSE is a separate package ,is enrichPathway dependent on DOSE?

Also I am getting only 9 enriched genes , but while using Reactome browser I am getting more enriched genes, does anyone has similar kind of experience?

Secondly I tried to do gsea , using following code:

> y <- gsePathway(gene, nPerm=1000,minGSSize = 150, pvalueCutoff = 0.2,pAdjustMethod = "BH", verbose = FALSE)
No gene set have size > 150 ...
--> return NULL...
> y <- gsePathway(gene, nPerm=1000,minGSSize = 120, pvalueCutoff = 0.2,pAdjustMethod = "BH", verbose = FALSE)
No gene set have size > 120 ...
--> return NULL...

Again I am unaware about the minGSSize,so I stripped of minGSSize and re-runned it didn’t throw any error but following was the output, says 0 enriched term:

>y <- gsePathway(gene, nPerm=1000, pvalueCutoff = 0.2,pAdjustMethod = "BH", verbose = FALSE, organism = "mouse")
 >y

> res <- as.data.frame(y)
Error in as.data.frame.default(y) : cannot coerce class "structure("gseaResult", package = "DOSE")" to a data.frame

so I guess minGSSize is significant , if this is so how can I solve this ?

Look forward for inputs

Hi thanks for your reply, clusterProfiler is not getting updated I have updated my R version to 3.4 and then installed ReactomePA & Clusterprofiler but I am getting the same old version of both the packages. Can anyone you now tell me what could be the solution for this? Here is the output of my command history:
