Good enough practices in scientific computing

Three years ago, Greg Wilson of Software Carpentry fame, along with fellow members of the Software Carpentry Community, published an article entitled Best Practices for Scientific Computing. This article is a great reference and covers all aspects of scientific computing. However, the paper could be intimidating to novices. To remedy this, Greg Wilson et al. recently published a follow-up paper

What are published effect sizes and study power in recent cognitive neuroscience and psychology?

Given the ongoing debate on the lack of reproducibility in many scientific fields, Szucs and Ioannidis (2017) analysed published records in cognitive neuroscience and experimental psychology journals to determine publication practices in these fields. The investigators used a text-mining approach to extract 26,841 records of degrees of freedom and t-values from 3,801 papers published between Jan 2011 to Aug 2015

GitHub: Setting up a version control repository – Part 1

We have been tracking along nicely with the tutorials on using Git for version control. So far, the lessons have focused on version controlling documents on a local computer, but another groovy feature of Git is it allows you and your collaborators to version control documents using GitHub. What is GitHub? GitHub is a web-based version control repository and is

Formalizing the definition of reproducibility and replicability

As highlighted in previous posts (e.g., 1, 2, 3), reproducibility and replicability are key features of scientific studies that have received considerable attention in the popular press and the scientific literature. However, as highlighted in a recent paper by Patil, Peng & Leek, there is no consensus on what these terms mean. Therefore, these authors took on the task of

What does research reproducibility mean?

Concerns about research reproducibility (or lack thereof) continue to escalate but it seems people can have quite different ideas about what research reproducibility means. In a perspectives editorial, Goodman and colleagues demonstrate concepts on reproducibility can be both precise: …reproducibility refers to the ability of a researcher to duplicate the results of a prior study using the same materials as

Software licenses demystified

Almost all scientists use computers on a daily basis. While some of the software they use will be proprietary, other software are conceived and developed by researchers themselves. In line with the current push for open and reproducible science, making scientific software available for inspection and use by other researchers is an important step in the research process. Furthermore, making
