Always nice when there is agreement between different neuroimaging packages. A quick block design analyzed in both AFNI and FSL – giving pretty similar results for the same participant. Both packages have distinct advantages. For AFNI: 1) it’s faster ; 2) it has more customizable options; 3) the viewer allows you to adjust […]

Creating automated snapshots of fMRI activation
There are plenty of times when you want to create snapshot images at a particular threshold so that you can quickly view the activation profiles of all participants within a given study. AFNI offers this functionality through a plugout_drive application where you can tell AFNI to change overlay, underlay, threshold, etc and even save the screenshots […]

Checking fMRI normalization
One of my first tasks when we switched our fMRI data analyses from our in-house code to using AFNI was to come up with a way of checking the alignment two MRI images. This could be either 1) EPI images to the anatomy or 2) individual subject anatomy to that of the standard space (MNI) […]
