Hi all!!

My name is Aritz Irizar and I am a postdoctoral fellow at the Icahn School of Medicine at Mount Sinai.

I'm trying to use EGSEA to generate pathway/gene-set enrichment results from a RNA seq dataset that contains two experimental groups (disease vs control) sampled at 4 timepoints. I perform 4 disease vs control contrasts, one for each timepoint and I feed the corresponding voom object and the contrast matrix to egsea in a for loop where, in each iteration, only one of the GSA methods is used so I can see which of them work and which give an error.

For some reason, 9 of the 12 base GSA methods give an error (only CAMERA, ROAST and FRY seem to work). 

See the code and the errors below please:

#generate gene-level voom object

dge_gene <- DGEList(counts = gcounts, genes = gannots)
dge_gene <- dge_gene[rowSums(cpm(dge_gene) > 0.2) > 5, keep.lib.sizes = F]
dge_gene <- calcNormFactors(dge_gene)

#build model for differential expression analysis

diffexpr_model <- model.matrix(~ ctrl_disease + day + RIN + total_RNA_ug + ctrl_disease:day, data = phenotypes)
colnames(diffexpr_model) <- make.names(colnames(diffexpr_model))

#perform voom transformation
pdf("diffexpr_voom_plot.pdf")
gene_voom <- voom(dge_gene, design = diffexpr_model, plot = TRUE, span = 0.5)
dev.off()

#subset voom object to contain only genes with an Entrez Gene ID
entrez_voom <- gene_voom[which(!is.na(gene_voom$genes$EntrezID)),]
entrez_voom <- entrez_voom[-c(which(duplicated(entrez_voom$genes$EntrezID))),]
rownames(entrez_voom) <- entrez_voom$genes$EntrezID
rownames(entrez_voom$genes) <- entrez_voom$genes$EntrezID

#build gene-set collections to compute enrichment for

murine_gs_annots <- buildIdx(entrezIDs = entrez_voom$genes$EntrezID, species = "mouse", msigdb.gsets = c("c2", "c5", "c7"), gsdb.gsets = "none", kegg.exclude = c("Metabolism"), min.size = 10)

#generate a symbolsMap

symbols_map <- entrez_voom$genes[, c(2,8)]
colnames(symbols_map) <- c("FeatureID", "Symbols")

#establish the list of independent gene-set enrichment methods for EGSEA to use

egsea_methods <- egsea.base()

#build contrasts for EGSEA
gsea_contrasts <- makeContrasts(
day5 = ctrl_diseaseD,
day12 = ctrl_diseaseD + ctrl_diseaseD.day12,
day17 = ctrl_diseaseD + ctrl_diseaseD.day17,
day36 = ctrl_diseaseD + ctrl_diseaseD.day36,
levels = diffexpr_model
)

#run EGSEA
#first pass to see which base GSA methods work in the dataset

egsea_dir_1 <- "./single_gsa_results"
unlink(egsea_dir_1, recursive = TRUE, force = TRUE)
dir.create(egsea_dir_1)

gsa_results_list <- list()

for(i in 1:length(egsea_methods)){
    tryCatch({
        print(i)
gsa_results <- egsea(voom.results = entrez_voom, contrasts = gsea_contrasts, gs.annots = murine_gs_annots, symbolsMap = symbols_map, baseGSEAs = egsea_methods[i], report = FALSE, print.base = FALSE, verbose = TRUE, keep.limma = FALSE, keep.set.score = TRUE, egsea.dir = egsea_dir_1, num.threads = 7)
gsa_results_list[[i]] <- gsa_results
}, error = function(e){cat("ERROR:", conditionMessage(e), "\n")})
}

Warning messages:
1: In mclapply(args.all, rungsva.contrast, mc.cores = num.workers) :
  all scheduled cores encountered errors in user code
2: In mclapply(args.all, rungsva.contrast, mc.cores = num.workers) :

4: In mclapply(args.all, rungsva.contrast, mc.cores = num.workers) :

From the errors, I cannot really figure out what went wrong in each case. Besides, I could really use some advice on what criteria to use when selecting the base GSA methods to include in the egsea run.

Any suggestions?

Thanks a lot,

Aritz

Hi Monther!!

Thanks for your quick reply.

I'm using EGSEA_1.2.0

Please find below a link to screenshot of the design and contrast matrices (it won't let me paste the whole matrices as text):

https://www.dropbox.com/s/0arppllf8n03109/design_and_contrast_matrices_screenshot.pdf?dl=0

Thanks a lot for your help and for developing such an useful package.

Best,

Aritz
