5 Brain Vision Analyzer 2 Tips and tricks that will help you get the best Product experience

1. View only the channels that belong to the region of interest.

Analyzer 2 Tricks and Tips: Create a montage by selecting the channels of interest

You can use montages to group channels and optimize their presentation. You can access the menu under “Display → Montages → Create Montage → Original”. You can then click on the channels of interest, in this example the midline channels, in order to include them in the montage. Afterwards you need to save the montage file (*.mont2).

Analyzer 2 Tricks and Tips: Change the montage under "Display Montage"

The montage can be changed under “Display Montage” in order to display the channels of interest only.

2.  Include a new frequency band in the FFT spectrum.Analyzer 2 Tricks and Tips: Views can be customized globally by using the option “Default View Settings”

You can change the view settings globally by selecting “File → Configuration → View Settings”. Click on “Grid View” and then select the tab “Bands”. Add the new frequency band to the table and afterwards select “Apply to all Views”. From now on all FFT graphical outputs will display these six frequency bands by default. The same procedure is valid to change features in other views.

3. The difference between Edit Parameters Reprocess and Edit Parameters Copy?Analyzer 2 Tricks and Tips: Edit Parameters/Reprocess and Edit Parameters/Copy can be found by right clicking on a history node

Edit Parameters/Reprocess and Edit Parameters/Copy allow you to re-run processing steps with different parameters. For example, you might decide to change the cutoff frequency for your filter. This can be done anywhere in the middle of your history tree because the history nodes below the edited node will be recalculated with their original parameters. If you use Edit Parameters/Reprocess, the original node is removed and replaced. If you use Edit Parameters/Copy, the original node is retained and you get a new node in you History Tree for the new parameters. You can find Edit Parameters/Reprocess and Edit Parameters/Copy by right clicking on a history node.

4. prefer to use a keyboard rather than a mouse to navigate my data?

Analyzer 2 Tricks and Tips: You can use keyboard shortcuts such as the ones illustrated here to navigate your data in BrainVision Analyzer 2. A full list of keyboard shortcuts can be found in the BrainVision Analyzer 2 User Manual

There are a number of keyboard shortcuts are available in Analyzer 2. For example, you can scroll through your continuous data or segments using Ctrl + the left and right arrow keys. You can increase or decrease the scaling by using Ctrl + the up and down arrows. A full list of keyboard shortcuts can be found in Appendix E of the Analyzer 2 User Manual.

5. Have you heard about transient views?

Analyzer 2 Tricks and Tips: Transient views can be found by right clicking in a portion of selected data

You can use transient views to quickly and conveniently display a complementary view of your data. Right click in a portion of selected data and choose “Transient Views”. Select the view that you would like. For example, choose FFT to display the spectral content of the data portion you selected.

Analyzer 2 Tricks and Tips: The selected transient view, in this case FFT, is displayed in a new window

You will get a new window containing the transient view; this window will have a dedicated toolbar. When you move this window through time, the transient view automatically adapts to the new content. Remember that this output is “transient”, i.e. it is not stored anywhere and no new node is created.
