Creating a Shiny application that enables user login can be useful for tailoring individual user experience and for analyzing user actions with profile-type data. With basic file I/O functions, it is possible to create a simple but insecure app that stores login names and passwords in text files. A much Read More
Recently I’ve been asked about how to submit parallel jobs to the cluster a couple times. It won’t take many steps if all one needs is embarrassing parallel (i.e., the program within each parallel job doesn’t depend on each other).
To my kids,
You don’t exist, but today I couldn’t stop thinking about you. You haven’t even been born yet (and honestly I don’t know if or when you will be), and there’s already so much I want to say to you, because the world you’ll be born in to Read More
I recently got around to reading the high-profile PNAS paper titled “Cluster failure: Why fMRI inferences for spatial extent have inflated false-positive rates” (Eklund et al. 2016), which called attention to the importance of properly processing and analyzing fMRI data.
This lead me to an earlier paper titled “Does parametric fMRI Read More
As I wrote about previously, CIFTI files are a new and useful file format for storing, analyzing and visualizing imaging data on the cortical surface AND subcortical areas (gray matter structures and cerebellum). Much of the imaging data available through the Human Connectome Project is in CIFTI format, so Read More
Like many mathematical topics, statistics can be persistently abstract and unintuitive. From dividing by n-1 instead of n, to proving results in infinite dimensional Hilbert spaces, statistics rarely goes down smooth on the first try. Most of the best statisticians take this challenge head on. They can quickly distill the Read More
Over the weekend my brother wanted to figure out his class schedule for the next semester. He is a veterinary medicine and zootechnology student at UNAM. For this upcoming semester there is a set of classes he has to take and each has 8 or so instructor options. The website Read More
