LabScribe2 software is a powerful recording and analysis software package offered by iWorx. LabScribe2 has an intuitive, user-friendly interface for setting up acquisition screens, calibrating signals and analyzing data. Up to 128 channels of data can be displayed simultaneously at sampling rates as high as 100,000 samples/second.
A comprehensive set of analysis routines have been preconfigured making data analysis and interpretation quick and easy. Specific analysis modules for cardiovascular research are available to analyze pressure signals, blood flow data, ECG recordings, ventricular pressure-volume loops and sonomicrometry dimension data.
LabScribe2 includes a scripting function for use if the built-in analysis tools fall short of what is required for your application. Scripting languages currently supported include: Dadisp, Python, MatLab, LabView, and C++.
LabScribe2 software displays data through a customizable, user-friendly, and intuitive interface. The number of input and computed channels, the display time, and scaling of the X and Y axes are just a few of the parameters that can be saved to a viewing template. Simply click one button to change from one view to another.
Real-time Online Calculations
Monitor and observe functional parameters during an experiment with an array of real-time calculations and user-defined computed channels. Labscribe2 software can calculate rates, min/max/mean values, systolic/diastolic values as well as derivatives and integrals in real-time. A unique channel math function allows users to create their own formulae for viewing signals in real-time.
Data can be analyzed and reduced in the Analysis window. Selections of data can be averaged and written to the LabScribe2 Journal or directly to a text file. For example, the software can be instructed to break a file up into five-minute pieces, determine the average heart rate for the data in each segment, and write those values to a report.
Mark data during an experiment with free-form text notes. These marks are searchable and appear in the field of data to which they apply. Marks are time locked to the record and can be used to “Go To” any marked region of the data. Marks can be preset and assigned as keyboard shortcuts for quick and easy annotation.
Specific time points and features of a signal can be AutoMarked for further analysis and validation. For example, the ECG AutoMark feature will place marks at the Q, R, S, T, and P waves. The blood pressure AutoMark will place marks at systolic and diastolic points, dichrotic notch and max/min dP/dt.
Any two channels can be displayed in XY format, online or offline. LabScribe2 software supports area measurements and segment slopes from such plots. And, of course, you can save the plots as pictures or text.
Settings files can be created for different experimental protocols. The number of input channels, calibration parameters, graph settings, computed channels, views and analysis protocols are all saved to a settings file.
LabScribe2 includes a Fast Fourier Transform feature for frequency analysis of any signal.
LabScribe2 supports various pacing and stimulation protocols with a built-in stimulator interface which allows delivery of a single, continuous, or train of pulses. Pulse durations, frequencies and amplitudes can be changed as the protocol is being delivered. The software also offers full control of digital I/O lines that can be used to count events, or control devices in the lab environment.
All recorded data can be exported to either a text file or a picture (.png, .jpg) making reports or posters much easier to create. Of course, you can always print your data from any window at any scale.
An optional import module is available so that data acquired from other acquisition systems can be analyzed with LabScribe’s powerful analysis routines.

Changing how data is displayed can easily be accomplished by setting up different views.
Data can be saved for several hours in one file. Marks can be entered to easily navigate to specific time points for data viewing and reduction.
Data from Automarks are sent to the journal from where they can be exported easily to Excel or another analytical program for further analysis.
Complex mathematical calculations are available for analyzing any cardiac signal. Examples include some of the pressure-volume loop algorithms included with LabScribe2.
FFT analysis can be performed on any signals. For example, heart rate variability can be calculated using either ECG or Blood pressure from this menu.
