Software to load EIT data from the three systems into Matlab
- ScouseTom - Developed in UCL lab, and the focus of this repository. Based around a Keithley 6221 current source and EEG recording system. This system is open source and further details are given in this repository
- KHU Mk 2.5 - Multi-Frequency EIT system. Helpful software for using this system can be found here
- SwissTom - Specifically the Pioneer set
Run the installer script load_data_installer.m, which installs the biosig library and adds the relevant directories to the matlab path. Run the command savepath afterwards to avoid having to do this again. DO NOT just add the lib folder as biosig contains lots of duplicate code.
To load data from the ScouseTom system first requires installation of the version of the biosig library found in this repository here. This was modified to save RAM when loading huge files.
The data is then processed by calling the function ScouseTom_LoadBV.m and directing it at a .bdf or .eeg file.
The KHU and SwissTom systems require only 'normal' Matlab.
The KHU data can be loaded using KHU_Load.m. Some extra input from the user may be required if there is information missing in the scanning directory. This can be entered manually, or is auto generated by the code here.
The SwissTom data is loaded using the file SwissTom_Load.m and should be self contained.
Small datasets for all three systems can be found in /resources/data with accompanying example usage of the processing code found in /example
