The Atlantis Source Connectivity Toolbox (ASCT) is an open-source software designed for a complete analysis of directional connectivity on EEG and MEG datasets.
The toolbox covers the complete signal processing, from raw data import to connectivity statistics and visualization. After setting up the analysis, i.e., defining the experimental design and adjusting parameters, a fully automatic mode of operation is available. The process can still be supervised at all stages, with a number of log files and a data viewer. Importantly, to enable reliable analysis of our own data, we provide recommendations for the majority of parameters. Our method underwent extensive testing with real experimental data and also using simulated and realistic signals.
ASCT works in Matlab environment. Download and unpack the archive. Add the directories into the Matlab path.
The ASCT requires FieldTrip to run. Other required toolboxes are shipped with the ASCT. Additionally for individual source models FreeSurfer is also required.
The analysis is launched with the EX_SETUP file, where all the analysis parameters and experimental desgn are defined. Sample ExSetup files can be found in the /templates directory of the ASCT.
Currently supported data formats are: bdf, eeglab (EEG), ctf, itab (MEG).
The up-to-date manual is currently under construction and is planned to be usable in Q2 2025
The project was supported by National Science Center (PL) and the Faculty of Philosophy, Jagiellonian University. Thank you!
