Installing the ERP PCA Toolkit

Today I’m raising awareness of a phenomenally helpful tool in ERP Research called the ERP PCA Toolkit.  In short, the PCA toolkit allows you perform temporal, spatial, and complex (e.g. temporo-spatial) analyses on ERP data.  Shown in the figure below is a quick temporal-spatial PCA on some ERP data for a go/no-go task.  The PCA […]

Parallelizing Freesurfer

Today I started running VBM and Freesurfer comparisons on a “new” dataset that everyone in our lab is particularly interested in moving forward.  The VBM was all carried out in SPM8 with the VBM8 toolbox. I particularly like the VBM8 toolbox because it makes use of the SPM8 DARTEL transformations, and it’s relatively easy to queue up […]

Visualizing Single Subject DTI Data (FSL)

A few posts ago, I described how to do some basic analyses of Diffusion data.  I realize now that I left off the visually cool factor of displaying individual subject data.  Once you complete the eddy_correct and dtifit steps in the previous post, several files will be generated for FA (fractional anisotropy), MD (mean diffusivity), […]
