Brain Entropy Mapping Toolbox: BENtbx (manual in pdf)

This toolkit is built for mapping brain entropy using fMRI. It uses several fuctions from ASLtbx.. We are now only releasing the packaged BENtbx through the GPL license. All correspondence can be addressed to: Ze Wang through (zewang at mail dot med dot upenn dot edu)

This toolkit is distributed "AS IS". This is no warranty to the accuracy of the package, and we are not responsible for any data interpretations or quality judgements though academic discussions are welcome, depending on how much free time we have. Please check this webpage for updates. We will unlikely send emails out unless there are significant changes.



BENtbx and the sample data provided in this website are free for academic use. The current version of BENtbx is based on Matlab 5.3 and above versions (MathWorks Inc, Natick MA) and SPM8 (The Wellcome Trust Centre for Neuroimaging at University College London). It's basically a collection of batch scripts, implementing a pipeline for processing fMRI data in order to get Sample entropy for each voxel. Some details about the fMRI-based brain entropy mapping can be found in the following reference, which should also be the appropriate citation for this toolbox:
