INTRODUCTION
MEATools is a collection of MATLABİ-based tools to analyze spike and field potential data from extracellular recordings with Multi-Electrode-Arrays, as produced by the NMI Reutlingen, and the MCRack (Vers. 1.3 and up) recording software. MCRack is part of the MEA-60 Systemİ, the ME16, ME32, ME64 and ME128 recording setup distributed by multichannel*systems.
For more information on Microelectrode Arrays see my MEA link page.
The MEA-Tools toolbox is meant to be an easy-to-use toolbox with graphical user interfaces (GUIs) on one hand and a script-based guide through some useful procedures on the other. These scripts can be expanded as needed to incorporate new data analysis or display features as required - and obviously depending on your knowledge of MATLAB (some MATLAB tutorials). We will incorporate some scripts into GUIs and add additional features ourselves as our own work progresses. If you think some of your own functions would be valuable extensions for the MEA-Tools and you have tested them within the MEA-Tools context we will be happy to make them available to other users and incorporate them in the download files. Please read the authors-guide for some of the concepts we use.
Generally, MEATools is arranged in 6 menus for spike analysis, LFP analysis, analysis of continuous records, supplementary data management, common display functions, and documentation respectively. Descriptions and help for the individual m-files used in this suite are available through MATLAB command line help functions (helpwin ?function>) or as HTML-documentation from the MEA-Tools menu. The HTML-doc will also show the cross-references between the files.
Almost all functions can also be called from the command line. See the function help for details.
SOME NOTES OF CAUTION:
- The MEA-Tools were tested for Matlab version 6.5 and higher, they will NOT work with lower versions!
- I hope I've found all bugs due to changes in 7.1. If you find more, please let me now.
- These tools were written under the assumption that you know the fundamental concepts and rules of MATLAB. You may safely assume that we have not found each and every bug and have not accounted for all possibilities for improper use of the MATLAB command language or the inconsistencies of MATLAB.
- Do not change variables, move, delete or close files while you are working with GUIs unless you are sure you know what you are doing.
- Working with such large files and amounts of data is very memory intensive. Get as much RAM as you can and arrange for ample swap space. Especially when analyzing LFPs I recommend that you copy the files you wish to process to a local harddisk.
- We do not take any liability for damages that may occurr through the use of these tools, directly or indirectly.
- Remember: garbage in - garbage out.
This list refers to the major menu items in the MEA-Tools title screen. The functions on which these are based and additional ones not assigned to an own menu entry are described in a separate list/HTML-reference included in the meatools.zip file.Tools summaries:

most recent MEA-Tools update: Sep 28th 2007 -- If
you send me an email egert@biologie.uni-freiburg.de
I will inform you about updates of these files.
- Download the m-file for semi-automatic installation: installmeatools.m
- Download the demo-movie mat-files (~9.3 MB), you need these to run the sample displays in the 'Display Functions' menu under matlab.
- Installation instructions (latest version of 9/28/2007)
The development of the MEA-Tools library was
funded in part by grant no. 0310965 and 0310964D from the BMBF, Univ. Freiburg
