  • Question: Multi omics dataset analyses, where to start? And methods to use?

    I have been given a dataset containing the following information: Species data was collected from Daphnia magna, the data consists of transcriptomic data (RNA-Seq) and polar metabolomic data (DIMS). This information was collected under 2 conditions, 1 = treatment with an unknown metal ion. 2 = treatment with an unknown metal nanoparticle. Data was collected over three time points; early (hours), intermediate, late (days). The experiment was repeated for multiple biological replicates. The task we have been given is to use statistics, machine learning, and bioinformatics knowledge to look for genes and metabolites that co-vary across conditions and in response to perturbations in an animal system.

    The data provided is in tsv format and contains the following: - Information on genes monitored including gene ID, gene family information, and information on functions. - Similar information for metabolites including empirical information, functional information and peaks in measurements. - Two other tsv files describing the change in gene expression over time for each individual and condition and another for metabolite data describing the same changes. This is all the information and instruction we have been given, we have 3 days to analyse the dataset. Could anyone suggest where to start looking for a method to start analysing this data? As we have covered limited machine learning, so our knowledge is limited at this time. Any advice on methods / resources would be greatly appreciated.

    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
