Bruno ColombetWhat is a montage?
AnyWave allows to set a list of channels that will be sent to views for display.
That is called a montage.
The montage can also be sent modules designed to apply signal processing algorithms on data.
default montage
The first time you open a file, AnyWave will get all the channels found in it and add them to a list called the default montage.
So the first time you will visualize all channels found in the file.
Edit montage
To open the montage editor click on Edit Montage button in the toolbar just below the menu bar:
Montage Editor
On the left side you have all the channels found in the file, called as recorded channels.
On the right side you have the current montage, ie the list of channels sent to signal views and modules.
You can manually select channels on the left side then click on the big blue arrow button to add them to the current montage.
This can also be done using the mouse and dragging channels from the left list to the right one.
By doing so the channels will be added at the end of the current montage.
The Up and Down buttons on the rigth part of the GUI allow to reorder channels in the current montage.
That action is also possible by drag and dropping signals in the list using the mouse.
There are more buttons allowing to quickly add or remove channels by their types, reordering them and so on.
Saving Montage for further use
Once you have set your montage, it is automatically saved along with the data file and will be used automatically the next time you open that file.
You can also save it giving a specific name using the Save button.
By doing so, AnyWave will propose to save your montage in a common location called Montages.
This is a folder created for you by AnyWave in your home directory under the AnyWave main folder.
That way you can save montage files in a common place and apply then to other data files.
That will save time redoing the Montage you want for similar recorded data files.
Quick montage
Click on the Load Montage button to quickly set a previously saved montage and apply it to the current data file :
Make you montage based on the helmet template
For EEG or MEG channels, it is possible do select the channels you want to use in your montage directly by clicking on the sensors on the 2D template display.
Note that the option is only available if AnyWave finds a matching template.
Click on the button:
Example using a MEG SQUID system template:
Note that if your file contains sensors of different types that could be in a template, for example EEG and MEG simultaneous recording, AnyWave will ask you what modality to use to create the Montage.
The GUI displays the sensors.
Click on a sensor to select it. The sensor will go red.
You can also select a region of sensors by pressing and holding the CTRL key and then drawing around the sensors. When the mouse button is released the sensors inside the drawn zone will be selected.
Example:
