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 […]

How to Analyze Diffusion Tensor Imaging Data (Review)

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 […]

Example use of DTIprep for DWI Quality Checking

In a previous post, we covered using DTIprep for preprocessing of diffusion weighted imaging (DWI) data.  I’ve written a quick script (below) to automate DTIprep for the purposes of running the default QC check.  My workflow has DICOM data automatically downloaded from our PACS server, then automatically converted to NIFTI format, and then organized in the […]

DTIprep for Preprocessing of DWI Data

As I’ve mentioned before, it’s a good idea to do some preprocessing on your diffusion imaging data!  Previous tutorials have covered using AFNI’s built-in tools (Part 1, Part 2, Part 3) as well as the very formidable TORTOISE (Part 1, Part 2, Part 3).  As with most things in NeuroImaging, you have many options when […]
