Chapter 2. Continuous signal acquisition and off-line spike sorting

Legend:

1	- Control Tab 0 switches between Continuous (this chapter) and Triggered acquisition (Chapter 3)
2	- Control switch for X axis scale (samples or absolute time is used in graphs and PSTH)
3	- Raw signal graph
4	- Spike locator (the color of the dot corresponds to the color of the spike shape in 13)
5	- Control Tab 1 (basic I/O parameters)
6	- Group indicators for automation: Signal THR – is the voltage threshold level for spike detection algorithm; Batch № – is a number for the data chunk that is currently being processed; SPK found – total number of spikes detected at the processing data set; Hist THR – is the level to threshold norm histogram (need to determine the number of classes); Peak width – specifies the number of consecutive data points used in the quadratic least squares fit for finding peaks at the norm histogram; Sensitivity – is an important parameter for adjusting the construction of norm histogram, thus influencing the determination of the number of clusters. Tolerant range is 1,8-3,3 (Default is 2.6, most common for different types of signals and acquisitions). SPK show – specifies the number of spike shapes to be visualized in each window of Shapes Tab indicator.
7	- Control Tab 2 (FCM status and performance information).
8	- Information panel for number of clusters and features used.
9	- Control button “TEST” to RUN clustering/classification algorithm
10	- Control button “on-line” to RUN online classifier
11	- Group indicator of data elaboration
12	- Control button to stop the program
13	- Control Tab 3 (visualization and statistics)
14	- Information about detected and accepted spikes
15	- Squares at the top left corner of each graph are controls to change the color of the class
16	- Sliding bar to navigate “Raw signal graph”
