Amplitude is shown on a color scale that can be configured through the view settings.įFT Band Export: Like the Peak Export this solution can be used to export single-trial data from a selected frequency range.

The solution is using the time-frequency view in Analyzer 2 to display trial number on the ordinate and time on the abscissa. It will display all segments stacked on top of each other (see Figure 2). You can do this with the Stacked Plot solution. For example, to estimate the variability of components across segments or to visually inspect a set of trials at once. There are solutions for time, frequency, or time-frequency domain exports.īefore the detection and export of peaks, it often makes sense to assess the ERP on a single trial level. Likewise, where Area Information and Peak Information Export modules work on averaged datasets, you can export data from single trials with the solutions described in the section Solutions for exports below. It allows you to place Peak markers at the maximum and/or minimum in a certain interval of each segment. The Peak Detection transformation for example, detects peaks on averaged data and the MinMax Marker solution on a single trial level. If you are interested in a demonstration of the solution, feel free to watch the recording of our webinar about “Sleep Research and Sleep Scoring Solution”. This solution will be available from our website from November 2021. The approved scores remain as markers in the dataset and can be used for Segmentation in a sleep-informed analysis in Analyzer 2. It summarizes important sleep parameters such as sleep latency, sleep efficiency, duration of stages and composition of sleep cycles. Once scoring is finished, a Sleep Report can be generated.

A full night hypnogram displaying all scores can be opened in a Microsoft Excel® sheet. The frequency-spectra or topography can be displayed simultaneously to support the scorer. You can navigate the sleep data in steps of the desired scoring interval (typically 30 seconds). The Sleep Scoring solution recognizes these markers and allows you to edit them. Its description indicates the type of physiological state i.e., sleep stage N1, N2, N3, N4, REM, or Wake or the absence of a score (None). For this purpose, we introduced the SleepStage marker dedicated to sleep research. Our Sleep Scoring solution allows you to manually score your data or inspect and edit imported sleep scores.

If you are a sleep researcher, you might be interested to know how to score and use sleep stages in Analyzer 2. Either way you only need to run the installer and open Analyzer 2 to have them in your Solutions ribbon menu (see below).

You have the option to download all of them at once or only individual ones. Most popular solutions can be directly downloaded from our website. Once they are installed you can use them almost as any other transformation. Solutions are free of charge for any Analyzer 2 user. They are usually created in first response to a frequently needed functionality and over time, we have grown a significant library of them.

At Brain Products Scientific Support, we offer a variety of extensions to Analyzer 2 that fill in this gap. As scientific methodology is rapidly evolving, occasionally researchers will miss a function or method that is not implemented as a transformation. Analysis pipelines created from the rich collection of Transformations cover most analysis needs while being extremely memory efficient. BrainVision Analyzer 2 is appreciated for its easy-to-use yet powerful signal processing ability.
