Extract is a tool for data visualisation, selection, and analysis.
To load files either drag and drop or navigate to the “Extracted” folder containing pre-processed files. These files should be located in your root folder (i.e. the folder where your original files are saved).
Visualise your data on the Extract dashboard and change data segments using the time slider.
Analysis workflows are listed under the workflows window. Select by double clicking on the module of interest.
This tutorial video takes you through the process of saving your results in the Extract module.
|Run||Loads the data specified by the file path.|
|Workflows||Lists of current analysis modules.|
|Sampling freq||Displays the sampling frequency in Hertz.|
|Wave file||Check this option to load raw waveform files (e.g. arterial blood pressure, doppler velocity waveforms).|
|Bold||Check this option to display data using bold lines.|
|Comments||Check this option to display file annotations. This function is only available for file formats that store annotations.|
|Erase last entry||Erases the last exported data entry.|
|Time cursor||Defines the time window to display.|
|Launches the help page.|
|Simple statistics||Performs basic statistical calculations.|
|Pressure flow transfer function||Determines the linear transfer function between beat-to-beat arterial blood pressure and beat-to-beat blood velocity time series.|
|Waveform transfer function||Determines the linear transfer function between pairs of waveforms.|
|Carbon dioxide reactivity||Estimates the vascular reactivity to carbon dioxide.|
|Pulse wave velocity||Estimates the velocity at which the arterial pulse propagates through the arterial system.|
|Critical closing pressure||Estimates the critical closing pressure defined as the internal pressure at which a blood vessel collapses and closes completely.|
|Autoregulation index||Calculates the cerebral autoregulatory index.|
|Pressure cardiac interval transfer function||Determines the linear transfer function between beat-to-beat blood pressure and beat-to-beat cardiac intervals time series.|
|Heart rate variability (frequency domain)||Estimates heart rate variability in the frequency domain.|
|Heart rate variability (time domain)||Estimates heart rate variability in the time domain.|
|Sympathetic neural activity analysis||Determines the common physiological parameters associated with muscle sympathetic nerve recordings.|
|Power spectral analysis||Computes the Power Spectrum of the input sequence.|
