Overview LabScribeNI is a
powerful recording and analysis software package developed by iWorx.
LabScribeNI 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.
New Features in LabSribe3 Software
The latest release, LabScribeNI includes a number of additional
user-friendly acquisition features, user interface enhancements,
powerful analysis capabilities and automated post-processing routines.
New features in this powerful recording and analysis software
include:
- Faster loading and processing times, especially important
for saving long data files, such as those found in telemetry studies
- New look and feel graphical user interface and function
icons streamline graphical user interface
- New toolbar shortcuts provide easy access to Sequences and
Views
- More display editing options provide flexibility in
presenting various data components
- Added flexibility in organizing format and data, including
tables, in the Lab Journal
- Ability to remove unneeded channel bars on the display to
increase viewable area for signals
- Enhanced analysis and reporting with the ability to execute
the mark dialog box and enter the associated text/comments after the
analysis is complete
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. Additional modules are
available for analyzing EEG data and metabolic function data.
LabScribe 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++.
Additional features inherent in LabScribe software:
Display
LabScribe 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.
Settings Files
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.
Real-Time Annotations
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, to all channels or a specific channel,
for quick and easy annotation. Marks can also be added and saved to
files while analyzing data (post-processing).
Meter Windows
Numerical data can be displayed in a meter window as a
digital value during data collection. This feature enhances the
acquisition experience by providing summary data from the traces being
collected. User-defined settings provide the option to display various
parameters from input traces such as mean, minimum, maximum, amplitude,
rate, etc. The frequency with which the value updates can be set by the
user.
Journal
LabScribe includes a Journal which is very similar to a text
editor. Text can be entered and edited in the Journal area and images
of traces and graphs from the raw data and computed channels can be
copied to the Journal. In addition to images, data values from the Main
and Analysis Windows can be added to the Journal. The Journal can be
printed, and its contents can be copied and pasted into other
applications. The Journal includes a table view and an editor view
making it easy to organize numerical data (table view) and generate
graphical reports (editor view). With the release of LabScribe V.3, the
Journal can be undocked and free-floating or can be re-positioned and
docked in different locations on the screen.
XY Window
Any two channels can be displayed in XY format, online or offline.
LabScribe supports area measurements and segment slopes from such
plots. And, of course, you can save the plots as pictures or text. With
the release of LabScribe V.3, XY windows can be undocked and
free-floating or can be re-positioned and docked in different locations
on the screen.
Real-time Online Calculations
Monitor and observe functional parameters during an experiment with an
array of real-time calculations and user-defined computed channels.
Labscribe 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 Reduction
Data can be analyzed and reduced in the Analysis window. Selections of
data can be averaged and written to the LabScribe 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.
Advanced Analysis
Various modules have been designed to speed up and simplify the
analysis of more complex sets of data. For example, our ECG module will
automatically determine the location of the fiducial points of an ECG
signal like the Q, R, S, T, and P waves. It will also calculate an
array of parameters like based on these time points (durations,
amplitudes, etc.). Analysis modules are available for many different
applications including cardiovascular function (ECG, Pressure,
Pressure-Volume), cognitive neuroscience (EEG), and metabolic function
(O2/CO2 monitoring at rest and during exercise).
FFT Analysis
LabScribe includes a Fast Fourier Transform feature for frequency
analysis of any signal.
Input/Output
LabScribe 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.
Binary File Structure:
A new binary file structure was introduced with LabScribe V.3 allowing
for much faster loading and processing times for data files. This
would, for example, be particularly beneficial for researchers who are
saving considerably large data files. This might apply to investigators
performing long-term telemetry studies as well as shorter protocols
with large numbers of channels and high sampling rates.
Export
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.
Import
An optional import module is available so that data acquired from other
acquisition systems can be analyzed with LabScribe’s powerful
analysis routines.
