  • High throughput Gene Ontology enrichment API

    A bioinformatics question: I have been doing more and more Gene Ontology (GO) work, specifically, I am looking for enriched terms in my various gene sets. I usually go through the web-based programs like DAVID or Babelomics. However, I now need a high-throughput approach, but was disappointed to only find GO::TermFinder on CPAN.

    There are plenty of GO handlers available on CPAN, but far fewer analytical tools, and there are many listed on GO.org, but most are web-based... so I wondered if anyone had any experience of doing GO term enrichment on many, many groups of genes?
    1. Any particular API I should use?
    2. Any particular problems I should look out for?
    3. Is there another web-based program I should think about?
    4. Is there a downloadable program that might be a good alternate? (i.e. a commandline based one that I can automate usage of?)


    Any help or advice much appreciated!

    NB: I have also cross-posted a similar question on PerlMonks...

    Hi,

    I'd personally recommend using either the topGO or GOstats packages from Bioconductor. They're both quite amenable to being used in a high-throughput analysis pipeline, although to get the most out of them you'll want to be comfortable in R.

      Thanks for the tip, I hadn't been through Bioconductor yet.

        You might also check out GeneAnswers (also in R).

          Exploring the Dynamics of the Tumor Microenvironment
          by seqadmin




          The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

          Exploring Human Diversity Through Large-Scale Omics
          by seqadmin


          In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
