One of the best things about AI coding tools is that I no longer have to endure frustration trying to figure out how to parse XML files and write SQL queries.

It's really nice when people actually use software that you create. This is an updated usage figure for the MRIQC.org Web API showing continued usage for the last 7 years, with more than half a million unique BOLD images in BIDS datasets! If you aren't already using MRIQC, check it out!

Our new paper is out! It offers a tool to assess collinearity impact on contrast estimates
*and*
uses simulations + MID data to show how common collinearity avoidance strategies can bias results.

Unintended bias in the pursuit of collinearity solutions in fMRI analysis
Abstract. In task functional magnetic resonance imaging (fMRI), collinearity between task regressors in time series models may impact power. When collinearity is identified after data collection, rese...

I know that citation statistics are faulty indicator, but I have to say that there is something humbling in knowing that people have decided 100,000 times to cite a paper that I was involved in.
