AFNI: what a long strange trip it's been

Abstract

AFNI is an open source software package for the analysis and display of functional MRI data. It originated in 1994 to meet the specific needs of researchers at the Medical College of Wisconsin, in particular the mapping of activation maps to Talairach-Tournoux space, but has been expanded steadily since then into a wide-ranging set of tool for FMRI data analyses. AFNI was the first platform for real-time 3D functional activation and registration calculations. One of AFNI's main strengths is its flexibility and transparency. In recent years, significant efforts have been made to increase the user-friendliness of AFNI's FMRI processing stream, with the introduction of "super-scripts" to setup the entire analysis, and graphical front-ends for these managers.

The AFNI graphical user interface (on OS X), with the individual subject InstaCorr module setup window shown, and the InstaCorr results from clicking in the posterior cingulate region (at the crosshair location) overlaid on the subject’s SPGR volume—un-thresholded in slice views and thresholded at r > 0.6 in a 3D see-thru volume rendered view. The sagittal slice viewer shows the AFNI controls which have been turned off (for de-cluttering) in the other image windows.
