Continuously Recorded Data

The continuous data type is used in NeuroExplorer to store the data that has been continuously recorded (LFP, EEG, EMG, etc.).

The following figure shows continuous variables shown in 1D Viewer:

Continuous data may not be imported by default from the data files created by the data acquisition systems. Use View | Data Import Options menu command to specify which data types NeuroExplorer will import from the data files.

Continuous variables can be used in the analyses listed in Analyses of Continuous Data folder of Analyses panel:

Limitations

Internally, each data point of the continuous variable is stored as a 2-byte integer or as a 4-byte floating point number. The maximum number of values (in each continuous variable) in NeuroExplorer is about 2.1 billion (2^31).

Viewers

You can view continuous variables in the graphical display (View | 1D Data Viewer menu command, see figure above).

Numerical values of the continuous variables are shown in the Continuous sheet of the Data view.
