책소개

We present MultiElec, an open source MATLAB based application for data analysis
of microelectrode array (MEA) recordings. MultiElec displays an extremely
user-friendly graphic user interface (GUI) that allows the simultaneous display and
analysis of voltage traces for 60 electrodes and includes functions for
activation-time determination, the production of activation- time heat maps with
activation time and isoline display. Furthermore, local conduction velocities are
semi-automatically calculated along with their corresponding vector plots. MultiElec
allows ad hoc signal suppression, enabling the user to easily and efficiently handle
signal artefacts and for incomplete data sets to be analysed. Voltage traces and
heat maps can be simply exported for figure production and presentation. In
addition, our platform is able to produce 3D videos of signal progression over all
60 electrodes. Functions are controlled entirely by a single GUI with no need for
command line input or any understanding of MATLAB code. MultiElec is open
source under the terms of the GNU General Public License as published by the
Free Software Foundation, version 3. Both the program and source code are
available to download from http://www.cancer.manchester.ac.uk/MultiElec/.
