NIS-Elements makes fluorescence and brightfield photodocumentation easy and intuitive, and offers extensive data management functions. The software’s interface is designed to simplify workflow, and delivers fast image acquisition speeds via direct streaming RAM to record rapid biological events. It provides complete control over Nikon motorized microscopes and other devices with powerful functions like a zoom control linked to calibration.

Selectable Layout Interface

NIS-Elements comes with the built-in layouts “Full Screen” and “Docked Controls.” Layouts of all windows and toolbars can be freely customized by the user and saved. Switching between layouts is achieved by a single mouse click.

Acquisition Color Setting

Color modification can be easily set with the LUT (look-up table). Indexed-color pixels are mapped into a selected set of true color values. The histogram, threshold, gamma parameter, and brightness of RGB components are adjustable. Modifications on live image processing can be easily accomplished on the GUI.

Data Management

NIS-Elements has a powerful built-in image database. The database supports image and meta-data, allowing users to create report templates or direct printed and PDF based reports. Various databases and tables can easily be created and images can be saved to the database via one simple mouse click.

In addition, filtering, sorting and multiple grouping can all be performed through the GUI's drag and drop functionality. Detail, thumbnail, icon and grid views are available on both the database image and the images on the file system.

NIS-Elements uses a sophisticated image documentation structure making it possible to achieve non-destructive archiving of image data including annotation (arrows, lines, text notes), measurement data, binary data for storing results of threshold or classification processes, and meta-data information for recording acquisition and device conditions at the time of image acquisition.

Flexibility in tailoring the software for specific applications is possible through simple built-in macro recording and the Advanced Macro Builder.

Report Generation

Report Generator enables the user to create customized reports containing images, database descriptions, measured data, user texts, and graphics.

PDF format files can be created directly from NIS-Elements.

Easy Access to Image Controls

All vital controls can be accessed by minimal mouse clicks.

Color Adjustment

NIS-Elements is suitable for hue adjustment, independently for each color, transforming the color image to one of the RGB or HSI components.

Color adjustments include:

• Contrast
• Background subtraction
• Component mix

NIS-Elements BR is powerful enough to handle 4D (X, Y, X, T), (X,Y,Z, Lambda (wavelength)) experiments quickly and flawlessly. This guarantees high-throughput and efficient workflow.

Multi-layer Document Structure

Each document (Image windows) is a three-tiered layer structure, and is therefore ideally suited for analysis. Multiple layer save is available with JPEG2000/ND2/LIM format.

NIS-Elements can work for all common file formats, such as JPEG2000, ND2, TIFF, JFF, JPG, JTF, BMP, LIM, AVI, ICS/IDS. ND2 is a special format for NIS-Elements. ND2 allows storing sequences of images acquired during ND experiments. It contains information about the hardware settings and the experiment conditions and settings.

ND Viewer (Multidimensional image display)

Easy-to-use parameters for multi-dimension image operation are located on the frame of the screen.

Process

Once a multi-dimensional image is acquired, it can be analyzed via NIS-Elements’ multiple processing functions.

ND Tools

A series of images from timelapse acquisition, or captured Z-stack images, can be easily converted to ND2 format. The converted images can be viewed and processed using features of NIS-Elements multidimensional document.

NIS-Elements innovative analysis capabilities include object counting, automated measurements, region of intent measurements and time measurements including image ratioing of multi-channel images.

Image Segmentation

Using the RGB or HSI color spaces, NIS-Elements can segment the image and create binary images. Using the binary image, Automatic Measurement records length, area, angle and colorimetry.

Automatic Measurement

Using binary objects, NIS-Elements can automatically measure sets of length, area, density and colorimetry parameters. About 30 different object features can be measured.

Interactive Measurement

The measurement is performed by, for example, directly drawing two parallel lines on the screen. Features are available from: taxonomy, counts, length, semiaxes, area, angle or profile and all output statistics and histograms can be exported to MS Excel.

Profile

There are five possible interactive profile measurements: free line, two-point line, horizontal line, vertical line, and polyline.

Classifier

Classifier allows segmentation of the image pixels according to different user-defined classes, and is based on different pixel features such as intensity values, RGB values, HIS values, or RGB values ignoring intensity. The classifier enables data to be saved in separate files.

Time Measurement

Time measurement records the average pixel intensities within defined probes during a time interval and can be performed on live camera signals.

Non-destructive measurements across time can be performed on live camera signals. Time Measurement records the average pixel intensities within defined probes during a time interval. Analysis can be performed pre- or post capture, with assurance that the specimen will live on after acquisition.

The software also handles:

• Single, dual, multiple fluorophores
• Ratiometrics
