Stop macOS Catalina 10.15 from hounding you about bash

You may have just upgraded to macOS Catalina 10.15 and noticed that EVERY. SINGLE. TIME. YOU. OPEN. THE. TERMINAL. You get a warning about changing the default shell to zsh instead of bash. There’s an Apple help page about it, but in case you just wanted to google the answer and find it here, the […]

Aligning Partial Volume fMRI in AFNI

One of the benefits of high-resolution fMRI (e.g. 7T+) is the ability to see smaller structures and even discern layers of the human cortex (examples: motor cortex and DLPFC). One of the frustrating things about doing sub-1mm resolution is that you’re often constrained to partial volume coverage. Which means that you generally have something that […]

Installing PyMVPA on Mac OS X

These instructions work on 10.10 (Yosemite) and 10.11 (El Capitain).  If things change in the future, I’ll try to update these instructions! Multi-voxel Pattern Analysis (MVPA) is hot right now.  Its users are the cool kids at conferences.  And if you want to join that crowd of researchers, you have a growing possibility of solutions […]

UCLA NeuroImaging Training Program

Just a quick reminder that the annual UCLA NeuroImaging Training Program is currently running.  You can download all of the materials (slides, video, etc) from previous years (like 2014) on their website. This years materials will be available after the workshop.  I also highly recommend, if you have some free time, checking out the live […]

Intersection Maps in AFNI
