AFNI is a functional imaging analysis package. It is funded by the NIMH, based in Bethesda, Maryland, and directed by Robert Cox. Like FSL, it is written in C, and it’s very common to use shell script [..]

Berkeley software distribution license. The BSD license is permissive, in that it allows you to modify and use the code without requiring that you use the same license. It allows you to distribute clo [..]

Contrast that is blood oxygen level dependent. When a brain area becomes active, blood flow increases to that area. It turns out that, with the blood flow increase, there is a change in the relative c [..]

BrainVISA is a sister project to NIPY. It also uses Python, and provides a carefully designed framework and automatic GUI for defining imaging processing workflows. It has tools to integrate command l [..]

Diffusion tensor imaging. DTI is rather poorly named, because it is a model of the diffusion signal, and an analysis method, rather than an imaging method. The simplest and most common diffusion tenso [..]

Diffusion-weighted imaging. DWI is the general term for MRI imaging designed to image diffusion processes. Sometimes reseachers use DTI to have the same meaning, but DTI is a common DWI signal model a [..]

The most widely-used open-source package for analyzing electrophysiological data. EEGlab is written in matlab and uses a GPL license.

Functional magnetic resonance imaging! It refers to MRI image acquisitions and analysis designed to look at brain function rather than structure. Most people use FMRI to refer to BOLD imaging in parti [..]

FSL is the FMRIB software library, written by the FMRIB analysis group, and directed by Steve Smith. Like AFNI, it is a large collection of C / C++ command line utilities that can be scripted with a c [..]

The GPL is the GNU general public license. It is one of the most commonly-used open-source sofware licenses. The distinctive feature of the GPL license is that it requires that any code derived from G [..]
