Sort Client
Sort Client is the primary MAP control program for real-time spike sorting based on digital signal processors (DSP).

Sort Client, enables the user to:

• Adjust the MAP operating parameters - automatic gain, thresholding, and cluster identification - in a three-dimensional principal component space
• Set the specific sorting parameters for each channel
• Control the MAP, which thresholds and sorts spikes, with time-amplitude-window discriminator boxes or by template matching
• Record spikes and continuous analog data (e.g. field potentials) to a file
• Easily export data files to NeuroExplorer, Matlab, or C++ programs

MAP Server
MAP Server is the low-level interface to the Multichannel Acquisition Processor (MAP) box. MAP Server transfers commands such as gain and filter changes or parameter settings from the various clients to the MAP. Server also distributes data coming from the MAP box to the client programs. It mediates communication between the clients, keeping them informed of commands sent to the MAP from other clients.

Event-triggered Field Potential GUI
The Event-triggered Field Potential Graphical User Interface is a MATLAB® display that plots a field potential signal around a spike or external event in real time. The field potential display can be averaged over all events or set to single-trial mode.

Front End Client

Front End Client (FEC) controls analog gain, filtering, and switching of the analog inputs from electrodes or microelectrode plates that go to various parts of the MAP system, such as the DSP channels and analog output channels. FEC supports new electrode layouts that you can define with a built-in graphical editor.

With FEC, you can:

• Assign "reference" channels to subsets of electrode channels for differential recording with the Plexon preamplifier (PBX)
• Select signals for the MAP Output (OUT) board
• Control MAP gain and filter settings for each channel

Graphical Activity Client
Graphical Activity Client (GAC) is a real-time observation tool for monitoring spike activity or continuous waveforms.

With GAC, you can:

• View up to six different displays:
  1. Raw events
  2. Activity graph Slow rate
  3. Integrated activity graph
  4. NI DAQ wave
  5. MMEP activity grid
• Visualize each display in real time in a different graphical or statistical manner, or both
• View multiple displays simultaneously at different time scales with different channels in each. You can also pause or unpause each display independently of one another

Grid Monitor
Grid Monitor (GridMon) displays spike-rate activity real time as an animated color grid.

With GridMon, you can:

• Display smoothly flowing spike activity
• Control the color scale and temporal integration
• View spike activity on a regularly-spaced array of electrodes, such as a multi-microelectrode plate (MMEP)

PeriEvent Client
Perievent Client (PEC) is a tool for displaying histograms and perievent rasters in real time.

With PEC, you can:

• Automatically view updated histogram and raster data immediately on the specified event channel when an event occurs
• Display perievent rasters for a specified number of previous trials beneath the PST histogram
• Control histogram limits, bin size, number of raster rows, and so on
• Display events in single or multichannel views
