Data analysis
Calculating growth rate from microbial growth curves using MATLAB
Growth curves are a ubiquitous technique in microbiology. Here is a primer on growth curve data analysis in MATLAB.
The difference between selection coefficient and relative growth rate
There are 2 ways to extract relative fitness from competitive growth assays. I discuss the difference between them and what they mean intuitively.
