similar to: Error using getBM() to query BioMart archives

I'm using 'getBM' function in Bioconductor package 'biomaRt' to retrieve gene ids based on known chromosome locations. The question is getBM just only return one gene id once a time, even a query is mapped to multiple genes. What's the criteria for picking that special one? [[alternative HTML version deleted]]

Steffen, When the new biomaRt tries to load it errors out because I do not have RMySQL installed. There is not a Windows binary for RMySQL and it does contain C code that I do not know how to build. I do not use the MySQL option in biomaRt. Does RMySQL need to be a required dependency? Below is my screen output and sessionINfo. require(biomaRt) Loading required package: biomaRt Loading required

Hi, I can run the code some days ago . But cant run now.  Problem 1: Output is ok ensembl = useDataset("hsapiens_gene_ensembl",mart=ensembl) utr5 = getSequence(chromosome=3, start=185514033, end=185535839, type="entrezgene",seqType="5utr", mart=ensembl)  Output :                                                                                                5utr

Dear R colleagues, I annotated a list of single nuclotide polymorphiosms (SNP) with the corresponding genes using biomaRt. The result is the following data.frame (pasted from R): snp ensembl_gene_id 1 rs8032583 2 rs1071600 ENSG00000101605 3 rs13406898 ENSG00000167165 4 rs7030479

Hi everyone, I am new to R-project. I did search through the list for my problem but i can't find it. I am sorry if this question has been asked. I would like to perform a correlation analysis between a hiv data and gene expression. Basically, i have a file that contains: hiv_name, start_position, end_position, chromosome. I would like to see if these data has anything to do with the

Hi !  Facing problem with " getSequence" commend .  when only biomaRt package loaded the following example working well  >mart <- useMart("ensembl",dataset="hsapiens_gene_ensembl") >seq = getSequence(id="BRCA1", type="hgnc_symbol", seqType="peptide", mart = mart) show(seq) but when i have loaded the seqinr, i got problem

Can biomaRt connect to data base "http://mirecords.umn.edu" or a branch of it ... for instance the validated miRNAs list ..? Thank you very much. Maura tutti i telefonini TIM! [[alternative HTML version deleted]]

I am running the last R version on SuSE 11.1. I installed the Bioconductor environment following the instructions on the web. As a consequence some core packages from Bioconductors were installed. I need to add some more packages. So I tried biomaRt as follows. It does not get installed correctly. Please see the following sequence. Thank you in advance. Maura >

Dear Forum my machine runs Ubuntu 9.04. I am trying to install Biomart, what I realize is that something is missing and it can't install XML, RCurl but I don't know what more to do, I looked in previous posts but I did not find infoprmation that helped. Thanks Andreia biocLite("biomaRt") Running biocinstall version 2.3.14 with R version 2.8.1 Your version of R requires version

I recently updated R 2.10.1 Patched (2010-02-20 r51163) This morning I reinstalled biomaRt using biocLite. Now I can no more connect to biomaRt and even the following instruction is hanging for a while until the same error message pops up. > listMarts() Error in value[[3L]](cond) : Request to BioMart web service failed. Verify if you are still connected to the internet. Alternatively the

Dear Sir/ma'am, I'm using R-3.4.4 and TCGAbiolinks package for the analysis of GDC data. Till today i have reintalled R and R studio for 5 times but one error comes when i analyze the GDC data at the step GDCprepare. the data i am using is not a legacy data of GDC data portal. I think the problem is with my Laptop only because i have run the same commands in another PC and there was no

I executed the following lines several times from a script as well as pasting them in an R shell. Systematically biomaRt is failing. The problem is to extract the 3UTR sequences corresponding to a vector containing 1941 Ensembl Transcript numbers (some are duplicated ... is this s problem ?) Please, find the failing instructions in the following including the ENST vector Any suggestion is

If I run an analysis which generates statistical tests on many SNPs I would naturally want to get more details on the most significant SNPs. Directly from within R one can get the information by loading RSNPer (from Bioconductor) and simply issuing a command SNPinfo(2073285). Unfortunately, the command cannot handle a vector and therefore only wants to do one at a time. I tried the lapply and
