Most models of neurobiological and behavioral data can be broken down into processes that evolve over time and static observation mappings. Given these evolution and observation mappings, the toolbox can be used to simulate data, perform statistical data analysis, optimize the experimental design, etc... In brief, the toolbox provides:
This toolbox runs in Matlab. Although it should run in all versions of Matlab, the toolbox has only been extensively tested on Matlab 2013 and higher.
Ideally, use Git to clone the repo of the toolbox on your computer:
cd ~/path/to/parentDirectory
git clone https://github.com/MBB-team/VBA-toolbox.gitYou will then be able to stay up to date with the latest versions using the command:
cd ~/path/to/parentDirectory/VBA-toolbox
git pullIf you don't want to install Git, you can alternatively download a zip of the latest stable release of the toolbox directly form the download page of the official website: http://mbb-team.github.io/VBA-toolbox/download.
cd ~/path/to/parentDirectory/VBA-toolbox
VBA_setup()Note that you might have do run VBA_setup() after an update of the toolbox (eg. after a git pull).
You can now try one of the demos or tutorials you can find in the VBA-toolbox/demos folder. If you have a recent version of Matlab (>= 2017), you can also run VBA_test() to check that everything works as intended on your system.
/ contains all the functions you can use directly in your scripts to call general routines like model simulation and inversion./core contains the sub-functions that implement the internal algorithms of the toolbox, like the variational estimation scheme. You should not use those functions directly!/demos contains a large selection of computational models (ie. evolution and observation functions) you can use directly or adapt to your hypothesis. You will also find in this folder a series of demos that implement those models and tutorials demonstrating the various features of the toolbox./legacy contains some old code that will soon disappear but we keep for backward compatibility./modules contains a set of tools that complement the toolbox, like DCM generators or advanced models and scripts used in publications./sandbox contains code in development that is not yet fully functional and / or tested. Feel free to test them, or wait a bit until they move to the core./tests contains unit testing functions. This code help us ensure that the toolbox does what we want it to do.../third-party contains code we did write ourselves but is needed by the toolbox./utils contains plenty of cool tools that you can use directly if you need, like random number generators, mathematical measures (eg. KL divergence), or nifty numerical tricks.Please visit the wiki pages for tutorials, demos, and advanced features descriptions.
You can also seek help on our dedicated forum. We will always be happy to help you with the toolbox if you need.
