Installing AFNI on Mac OS X 10.11 “El Capitain”

We’ve all been there, Apple releases a new Operating System and when you install it, you find out that your favorite programs don’t work on launch day or require some special install instructions.  Well if you’ve installed AFNI onto a Mac running 10.11, you may notice that some of the Python programs don’t fully work.

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 […]

Helpful fMRI QA Tools in AFNI

Apologies for the lack of updates lately!  It’s been… busy. I’ve written in the past about automatically making “snapshots” in AFNI (here) and even doing that without having AFNI taking over you entire screen using Xvfb (here).  These are one way of performing Quality Assurance (QA) on your data, by actually LOOKING at the activation […]

Parallelizing Tracula

By popular request, or rather the sheer number of hits the Parallelizing Freesurfer post, today we turn our attention to Tracula, the Freesurfer integrated solution for doing diffusion tensor imaging (DTI) tractography!  Tracula has a lot of nice features, one of my favorites is the ability to estimate 18 or so tracts in the brain by constraining […]

After my first year of blogging, I ran a “One Year Review” piece that covered all of the articles that I wrote in that first year.  And that article tends to get hit by search engines fairly often since it was published on December 3, 2013.  Sure, I meant to go back and do a […]
