  • GO enrichment for RNA-Seq

    I am looking for a way to display GO-enrichment of RNA-Seq (e.g. pie charts/graphs for the most enriched GO categories).

    I have used the R package GoSeq to identify the significantly enriched GO terms, but I would like to get more information than just a list of GOIDs.

    I was thinking of retrieving the genes associated with the enriched GOIDs and then use GoFinder to perform the enrichment analysis and plot the graph.

    How do I get the genes associated with the GOIDs from GoSeq?

    Thanks,
    PFS

    ps: I understand GoFinder will not take care of the length-bias due to RNA-Seq, but I figured that if I first perform the analysis with goseq, then grab only the genes associated with the GOIDs identified by goseq, and repeat the analysis with these genes only, I should be able to avoid the bias. Is that correct?

    The Impact of AI in Genomic Medicine
    by seqadmin



    Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

    Multiomics Techniques Advancing Disease Research
    by seqadmin


    New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”

    A major leap in the field has
