It is an annual event on quantixed to post the papers I have selected for what is now called MD9A8 (the module formerly known as MD997 Frontier Techniques and Research Skills in Biomedicine). Previous selections are grouped here. The list serves as a snapshot of interesting papers published in the previous 12 months or so. I hope it […]
Wordless Song: Benchmarking Wordle performance using R
A quick post about a puzzle called Wordle that is currently taking over the internet. It’s a mastermind-like game where the object is to guess an unknown 5-letter word. Puzzlers are encouraged to share their results after completing a puzzle. Here is an example for puzzle 192. So how do you know if your performance […]
Untitled: “The structural basis of…” titles for structural biology papers
This recent tweet made me chuckle. It does seem that many structural biology papers have a title that begins “The structural basis of…”. I took a quick PubMed survey to look at its popularity. First a search of “structural basis”[ti] AND “journal article”[pt] gives us the number of research papers with “structural basis” in the […]
Target II: Monitoring a running goal in R
As 2021 draws to a close, it’s time to check back in on a previous post. As a recap, Garmin Connect offered four challenges to run 3 x 505 km and 1 x 505 km, one in each of the four quarters of 2021. Completing all four would mean running 2021 km in 2021. I […]
Tips From The Blog XVI: fast check of two directories

How can we check that they have the same contents? I found myself in this situation recently during a server migration. Method 1: rsync To […]
What’s In The Box II: Wrapped but not streamed
In early December, Spotify users received a list, known as Spotify Wrapped, of the tracks they listened to most in 2021. As a committed non-streamer, I was a bit envious of these lists; so I decided to assemble my own list using my Music database. This was possible by comparing two snapshots of my Music […]

Well, quantixed did not want to miss out on the fun, so I came up with a list of my favourite 20 albums released in 2021. Top 20 Electric Looking Glass – Somewhere Flowers Grow Corduroy – Corduroy Divide […]
Line Up: Waffle plots for colocalisation data
Quantifying the degree of colocalisation of two signals in microscopy images is very tricky. Lots has been written on this topic, including in my book The Digital Cell. The focus of this post is on visualising colocalisation. One way to look at colocalisation is two think about two sets of objects and how many of […]
Seles II: Tennis coding challenge solution
In a previous post, I described a coding challenge sent to me by my colleague. Here is the challenge again: There is a tennis match between two players denoted 1, and 2. You are given a sequence of 1s and 2s whereby each number denotes a point won by player 1 or player 2 (e.g. […]
