  • biomaRt not connecting behind proxy

    Hi!

    I am facing an issue with biomaRt.I have tried posting this on Bioconductor support as well. I'm working behind a proxy and have modified the Renviron file to incorporate the proxy addresses and port. I have also used the RCurlOptions to feed in the proxy as suggested in the biomart vignette. I am using the useMart command as:

    ensembl<-useMart("ENSEMBL_MART_ENSEMBL", dataset="mmusculus_gene_ensembl", + host="www.ensembl.org")

    which doesn't throw any error. listMarts and listAttributes, everything works fine but when I actually come to getBM the connection is refused. The command that I'm using is (I'm following DESeq2 beginner's guide)

    genemap<-getBM(attributes=c("entrezgene", "ensembl_gene_id", + "mgi_symbol"), filters="ensembl_gene_id", + values=res24$ensembl, mart=ensembl) Error in value[3L] : Request to BioMart web service failed. Verify if you are still connected to the internet. Alternatively the BioMart web service is temporarily down.

    I can connect to ensembl and access the data on its ftp servers through browser.

    Any suggestions will be much appreciated. Thanks!

    Current Approaches to Protein Sequencing
    by seqadmin


    Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

    Strategies for Sequencing Challenging Samples
    by seqadmin


    Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
