What's New in 4.1 from 4.0 

This section describes (briefly) what is new or improved from the 4.0 version of EEGer (but not organized into any particular order).

• Layouts 
• EEGer now has the concept of 'layouts' which are the mapping of input, output, and screen display. Besides the 5-trace layout in 4.0, there are now 6-trace(with extra inhibit), 6-trace (with extra reward), and 8-trace layouts. There is a (unique) session plan for every layout/client.  Additional layouts are available for special purposes (such as screening).
• Electrode site locations 
• 10-10 and 10-20 head charts are user-selectable (and printable). You can now use 10-10 (modified) site locations. 
• Game tailoring 
• Therapists have  many options to tailor game actions and session parameters. These options can be persistent or single-session only changes. 
• Filters 
• Filters now go up to 50 Hz in 1/8 Hz steps. Therapists can configure the lowpass (upper) limit to 30, 40 or 50 Hz. 
• Peripheral data input
• Peripheral data input can now be selected (saved) and displayed from applicable input devices. 

• New games 
• 4mation is a picture grid filling game with a number of fill modes. You can even use your own pictures (BMP or JPEG). 
• Spectral Mirror is a client display of spectral data.

• Long-term display is a moving graph of EEG and/or peripheral data.

• Therapist spectral mirror
• This is a therapist display of spectral data.

• Tactile feedback 
• Tactile feedback works (using a sound card as the driver) with the T key bringing up a control menu. 
• Single computer option 
• A single computer can be both the Therapist and Client/game computer (using only the EGS games). The space bar toggles between game and therapist graphics. 
• Remote use 
• Remote use systems have user session controls set up by a Therapist. A USB memory device takes the place of a floppy so all the stored and summary data is returnable to the Therapist. 
• Volume controls 
• Volume (for EGS games) is now controlled from the Therapist keyboard. 
• Overall reward percentage 
• A new measure is computed/displayed that shows the percent time spent in a rewardable (no inhibits) state. This resolves the problem of trying to eyeball-measure this condition, especially when you have lots of traces to watch. 
• Autothreshold goals 
• Autothreshold (F11) goals are now changeable while running (using the G key for a popup menu). 
• Devices 
• More devices are supported for input. 
• Export 
• Summary data (1-second samples) can now be exported to an ASCII CSV file readable by Excel or other programs. 
• Output in a special format is automatically/manually created for the Results! Program.

• Bug fixes 
• Too many to list 
• Printing
•   Timing monitoring/overrun detection
•   Reports 
• Filtering
