DTI Statistics with TRACULA data (Part 1)

If you’re reading this post either you’re a loyal fan (yay!) or you’ve run Freesurfer (possibly in parallel) and processed your diffusion data in (hopefully TORTOISE) and then Tracula (also possibly in parallel) and you’re wondering where do you go from here.  I’m glad you’re here, that’s probably me talking to myself because I read my own blog […]

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 […]

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 […]

Getting started with Machine Learning

So we have to face it, Machine Learning is the buzzword of the year (multiple years?).  But where does one start learning?  Well assuming you’ve taking some stats classes in the past and words like regression don’t scare you off, you may be able to jump right in to some of the applicable textbooks out […]
