    Simpler data analysis with MetaR

    Hello,

    I wanted to introduce MetaR, a language to analyze RNA-Seq data and produce visualizations such as heatmaps. MetaR provides a language simpler to learn and use than R, yet generates full analysis scripts in R, using popular R/Bioconductor packagages (e.g., data.table, EdgeR, pheatmap). We find that on average 1 line of MetaR generates about 5-10 lines of R code. The language offers full auto-completion for table, columns, model or plot names, making it easier for beginners to get started.

    Below is a snapshot of an RNA-Seq analysis followed by construction of a heatmap with the MetaR language.

    This blog post has more details about motivations and design and links to a video demonstrating how to build a heatmap from a table of read counts with MetaR. For the technically inclined, MetaR is a composable language, which means that it is easy to extend with new instructions, expressions, or other language constructs, in ways that are not practical with traditional languages. You can even extend the language as you are writing a new script and realize you need a new kind of statement.

    Reply to 16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?

    The part about this topic feels surprisingly grounded, and the details on the page is the bit that made me slow down. I’d keep <a href="https://kinpict.com/">ai family photo generator</a> bookmarked for later.

    16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
    by SEQadmin2





    NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...
