View source for AnyWave:H2

=Purpose and usage=
The plugin computes the connectivity between channels using h2/r2 algorithms.<br/>
==Select the channels==
The first step is to select the channels of interest.<br/> 
If there is no selection when launching the plugin, a warning message will pop saying that all channels will be used for the computation.<br/>
==Select sections of data==
Insert markers on the data of interest using the Marking tool of AnyWave or used previous marked data.<br/>
To launch the plugin on a specific markers selection, use the markers list on the left side of the signal view:<br/>
* select the markers of interest in the lis.
* right click and choose Launc Process
* Pick the H2 process and launch.
==Computation parameters==

===Data input===
To speed up the computation you may want to downsampling the data. The default is to NOT downsample the data (x1).<br/>
<br/>
If you have marked data, you can specify which artefacted parts of the data to avoid in computation ''using the skip data using markers'' options:<br/>
* select the marker corresponding to the part to skip (ie 'artefact').
* click Skip button to add it to the list of markers to skip.
<br/>
In the same way, you can also specify on which particular marked data compute the connectivity:<br/>
* select the marker corresponding to a period of interest.
* click the Use button to add it to the list of markers to use for computation.
===Frequency bands===
You can compute the connectivity on different frequency bands.<br/>
By default, the ''AnyWave band'' is selected which means the filter options set in AnyWave will be used.<br/>
You can enable the different predefined bands and even change the frequency boundaries.<br/>

==Review resulting graphs==
When the computation is finished, the resuslts are saved to a MATLAB file located in the data file's folder.<br/>
Another plugin is automatically launched allowing you to browse the different connectivy graphs:<br/>
[[File:h2graphs_ui.png]]<br />
The UI propose all the graphs resulting from the computation. A graph for each frequency band.<br/>
You can see what algorihtm was used on what frequency band and the number of sections which is the number of selected part of data used for computation.<br/>
<br/>
Click on rows to select them and click on View to see the graphs.<br/>
=Batch mode=
The plugin is able to run in batch mode.<br/>
