    <subfield code="a">&lt;p&gt;The COCOHA Matlab Toolbox is a coding framework internally shared within the &lt;a href="https://cocoha.org/"&gt;COCOHA&lt;/a&gt; project.&amp;nbsp;It was written to standardize MATLAB data storage and decoding analysis for the project.&amp;nbsp;The&amp;nbsp;&lt;a href="https://gitlab.com/cocoha/cocoha-matlab-toolbox/blob/master/README"&gt;data structure&lt;/a&gt;&amp;nbsp;is based loosely on FieldTrip&amp;rsquo;s, but allows for the storage of multiple data&amp;nbsp;sources (e.g. audio/EEG) and provides flexibility in defining dimensions (e.g. channel, time, frequency, rate, scale, etc). Moreover, function calls that modify the contents of the data structure will append their user-defined parameters to the data.cfg cell array. This allows for&amp;nbsp;traceability of results.&lt;/p&gt;

&lt;p&gt;The functions in the toolbox allow for external functions to operate on the data structure in a robust and standardized way.&lt;/p&gt;

&lt;p&gt;The MATLAB components are designed for offline prototyping of decoding strategies. On the other&amp;nbsp;hand, realtime processing is primarily implemented with OpenViBE Python scripts. OpenViBE is used as&amp;nbsp;it provides drift correction, and its support for object-oriented programming allows better&amp;nbsp;modularity.&lt;/p&gt;

&lt;p&gt;The toolbox&amp;nbsp;is not designed to replace FieldTrip for more traditional M/EEG analyses, but rather as a means to supplement such analyses with a&amp;nbsp;support for decoding models. As such FieldTrip import capability is provided (and export capability is still pending).&lt;/p&gt;</subfield>
