BioReview is a utility that allows you to calculate and view session statistics for BioExplorer. Bio Review allows you to create reports, which can be saved, loaded and run on previously recorded sessions.

The BioReview User Interace is made up of the following components:

Main Menu
Signal Diagram
One or more Views

Each of these features are indicated below.

Main Menu

The Main Menu is located at the top of the BioReview application windows.

The menus are:

• Report
  • Update Sources: Updates the current report source obects from a session file. A typical use would be to add source objects to a report after it has been created.
  • Run: Runs the report on the currently open session
  • Run On Session: Runs the current report on a Session file.
  • Preferences... : Allows you to set program preferences
• Signal Diagram
  • Add Object : Allows you to add a new Design Object to the Signal Diagram
• View
  • Add Signal: Allows you to add a signal from the Signal Diagram to the current View.
  • Properties... : Allows you to set the properties for the current View (e.g. epoch, chart fonts and colors, etc.)
  • Print Epochs : Prints the contents of the upper portion of the current View in either chart or table format, depending on which format is selected.
  • Print Summary : Prints the contents of the lower portion of the current View, the summary statistics.
  • View / Export : Allows you to export the statistics or raw data of the signals contained in the current view.
  • View / Cancel Zoom : Resets the time span of the current view to the duration of the entire session. Also resets the chart axix so that all data can be displayed.

Signal Diagram

The Signal Diagram window in BioReview is used to graphically specify the signals you want to use in your report.

For example, the Signal Diagram above will calculate the alpha signal, amplitude , and coherence for two EEG channels.   Unlike the Signal Diagram in BioExplorer, you can only add Transform objects the BioReview's Signal Diagram.

View Window

The View window displays summary and epoch statistics for one or more signals.

The lower portion of the window displays summary statistics for each signal, calculated over the current time span.   The upper portion of the window displays the mean value over each epoch for each signal, in either chart or table format.

Time Span
You can change the start time, end time, and epoch length by choosing Properties from the View menu.   You can also change the time span by left clicking the mouse in the Chart and dragging it over the desired time span and amplitude range.   To return to the original full-session time span, choose 'Cancel Zoom' from the View menu.

Adding Signals
You can add a signal to the current view by choosing Add Signal from the View menu.   Statistics will not be displayed for newly added signals until you run the report on a session, by choosing 'Run' or 'Run on Session' from the Report menu.

Removing Signals
Remove a signal by selecting it in the Signal column with the mouse.   This will select the entire row.   Then press the Delete key to remove the signal.

Changing the Signal Order
You can change the order of the signals using the Table view.   Select the Table tab, and then simply drag the signal where you want it by clicking its column header and dragging with the mouse.

Display Name
You can set the display name for any signal by typing it into the Name column.   The display name is used by the chart legend (if enabled) and the table view.   It is also used to identify each signal when exporting data.

Threshold
You can set the threshold for each signal by typing it into the Threshold column.   BioReview will report the percentage of samples that are over and under this threshold over the current time span.

Scale
You can set a scale, or multiplier for each signal by entering it into the Scale column.   This can be useful if you want to view signals with different ranges on the same chart.   Exported statistics are also scaled by this value.

Enable/Disable Chart
You can set whether or not a signal is displayed in the Chart using the checkbox in the Chart column.

Color
Use this column to set the Chart color for each signal.
