This is re-posted from my newsletter, where I'll be posting from now on: https://blog.stephenturner.us/p/biorecap-r-package-for-summarizing-biorxiv-preprints-local-llm ---TL;DR I wrote an R package that summarizes recent bioRxiv preprints using a locally running LLM via Ollama+ollamar, and produces a summary HTML report from a parameterized RMarkdown template.

My new blog/newsletter ("Paired Ends") is now at blog.stephenturner.us. I'll be posting semi-regular updates and literature highlights in bioinformatics, computational biology, and data science, along with the occasional post on programming.

A while back I wrote this post about how I stay current in bioinformatics & genomics. That was nearly five years ago . A lot has changed since then. A few links are dead.

The first ever RStudio conference was held January 11-14, 2017 in Orlando, FL. For anyone else like me who spends hours each working day staring into an RStudio session, the conference was truly excellent . The speaker lineup was diverse and covered lots of areas related to development in R, including the tidyverse, the RStudio IDE, Shiny, htmlwidgets, and authoring with RMarkdown.

I recently stumbled across this collection of computational biology primers in Nature Biotechnology. Many of these are old, but they're still great resources to get a fundamental understanding of the topic. Here they are in no particular order.

I came across this awesome gist explaining how to syntax highlight code in Keynote. The same trick works for Powerpoint. Mac only. Install homebrew if you don’t have it already and brew install highlight. highlight -O rtf myfile.ext | pbcopy to highlight code to a formatted text converter in RTF output format, and copy the result to the system clipboard. Paste into Keynote or Powerpoint.

How many reads do I need? What's my sequencing depth? These are common questions I get all the time. Calculating how much sequence data you need to hit a target depth of coverage, or the inverse, what's the coverage depth given a set amount of sequencing, are both easy to answer with some basic algebra. Given one or the other, plus the genome size and read length/configuration, you can calculate either.

This is a guest post from VP Nagraj, a data scientist embedded within UVA’s Health Sciences Library, who runs our Data Analysis Support Hub (DASH) service. Last weekend I was fortunate enough to be able to participate in the first ever Shiny Developer Conference hosted by RStudio at Stanford University. I’ve built a handful of apps, and have taught an introductory workshop on Shiny.
