Analysis

• Waveform analyses including averaging, power spectra and waveform correlations
• Event analyses including INTH, PSTH, auto and cross correlations and phase histograms
• Automatically find data features including triggers and features in evoked, spontaneous activity and cyclical data with 'active' cursors - see a video demonstration
• Generate XY plots and data file channels holding measurements based on 'active' cursor feature detection, and output tables of measurement values
• Take absolute and relative measurements such as time points, data values, curve area, slope, max/minimuma, mean, modulus and peak to peak
• Quickly take time and amplitude measurements using the mouse pointer
• Derive 'virtual channels' from existing waveform and event channels defined by user-supplied expressions (channel arithmetic). Options include mathematical functions, spectral analysis and comparison operators

• Generate functions in 'virtual channels', including sine, square, triangle waves, envelopes and polynomials
• Process waveforms dynamically on- and off-line. Processes include rectify, smooth, DC remove, downsample, median filter and RMS amplitude
• Create editable temporary channels containing copied or derived data
• Digitally filter waveforms (FIR and IIR) with interactive filter design
• Interactively fit data with functions including exponential, Gaussian, polynomial, sinusoid and sigmoid
• Automate repetitive, multi-step and custom analyses using the script language
• Script advanced processes, for example hum removal from any number of waveform channels using the CED 4001-16 Mains Pulser
