Chapter Three- Exporting, Saving and Printing Images
The most convenient way to archive or document the complete information about your experiments is to generate reports.
However, you may just want to export only your gel or blot image(s) for presentation or publication purposes.
This chapter describes all the ways you can export an image, save and print images.
3.1 Saving Images
Images captured with genePIX software can be saved in several formats. To save an image simply press (touch-screen) or click on the following icon (Figure
26).
Figure 26- Save icon
A dialog box will pop up where you can enter a file name for your image. You can
also use the ‘Save as type’ drop down menu and select to save the image as a
Data (*sgd), TIFF image file (*tif), Windows Bitmap image file (*bmp) or a JPEG image file (*jpg) (Figure 27).
Figure 27- Saving dialog box
26
The default is set to Data (*.sgd) which is a secure file and GLP compliant. These files can only be opened or altered in Cleaver Scientific software packages such as geneQUANT. SGD files contain all the capture information such as lighting, filter, exposure times and many more complex details i.e. the camera serial number.
You can select to save the raw image as a TIFF (16 bit uncompressed or 8 bit compressed). This format is used when you require all the image data to be retained. This file option creates a larger file, but will allow you to analyse the image in other software packages.
To save the displayed image select between *.bmp and *.jpg formats N.B. *.BMP and *.jpg formats will save as 8-bit files and you will therefore lose quantitative data. This format should only be used for the export of visual information to presentation or word processing software, such as Microsoft Powerpoint or Microsoft Word.
3.1.1 Saving Annotations
Annotations can be saved as a .sgd file format. Select the Save/Load annotations icon to add annotations to an image from a saved .ANN file using the Load Annotation button (ANN. Annotation file) (Figure 28).
Figure 28- Saving Annotations icon
3.2 Printing Images
Images captured with genePIX software can be printed using a thermal printer or any other printer. To print an image you need to press (touch-screen) or click the following icon (Figure 29).
Figure 29- Print icon
27
A dialog box will appear showing a print preview. Select Print to print the image (Figure 30).
Figure 30- Print preview
3.3 Exporting Images to geneQUANT analysis software
Various file formats can be exported from genePIX to geneQUANT. Cleaver Scientific recommends uncompressed TIFF or .sgd to maintain quantification.
To export a captured or saved image simply select the ‘open selected images in geneQUANT’ button (Figure 31).

Glossary
The following glossary defines words used in this manual. Auto Capture- the software will configure the optimal exposure time for your
sample using the maximum number of greyscales from your camera.
Histogram- A graphed representation of brightness, or grey value, of an image. Image source- there are two types of image sources, original and processed. If
you have made enhancements to your image such as sharpening, smoothing and cropping an area this will alter the image source and the image will now be processed.
Iris- On a CMOS camera the iris is an adjustable aperture used to control the amount of light coming through the lens.
Dynamic fielding- The dynamic field function corrects for uneven illumination of light sources.
Speckle correction- will remove white speckles or ‘hot pixels’ (bright spots)
from the image.
