Doubt on annotation of ensembl ids in biomart using R 0 Hi All 🙂 I have a large list of unique ENSEMBL IDs (48,432) representing mouse genes, my goal only is to get attributes like gene name and ncbi id to build a dataset with expression data. However when using…

Hello! I am working on analyzing a dataset I created with the 10x Chromium Single Cell Multiome kit. In order to add gene annotation to the ATAC data, I am trying to install and use the “EnsDb.Mmusculus.v79” and “BSgenome.Mmusculus.UCSC.mm10” packages with bioconductor. The same ERROR has come up repeatedly whenever…

I tried several R packages (mygene, org.Hs.eg.db, biomaRt, EnsDb.Hsapiens.v79) to convert Ensembl.gene to gene.symbol, and found that the EnsDb.Hsapiens.v79 package / gene database provides the best conversion quality (in terms of being able to convert most of Ensembl.gene to gene.symbol).

Hi, I have a question about DESeq2 LFCshrinkage: Is it possible that some genes have a slightly higher LFC after shrinkage? It happened during my RNAseq DE analysis, I have very deeply sequenced samples with large base means. I tried visualizing using MAplot check, and it looks fine. I’m mainly…

Short answer is that I think for now you have to bypass some of the biomaRt functions, and create a Mart object yourself. So give this a try: library(biomaRt) phytozomeMart <- new(“Mart”, biomart = “phytozome_mart”, vschema = “zome_mart”, host = “https://phytozome.jgi.doe.gov:443/biomart/martservice”) The rest of your code should work using this…
