DeCyder™ 2D Software is an automated image analysis
software suite which enables detection, quantification,
matching and analysis of Ettan™ DIGE system gels. The
two-dimensional (2D) electrophoresis gels are used for
separating complex protein mixtures labelled with up to
three CyDye™ DIGE Fluor dyes.
The multiplex labeling enables detection of small differences
in protein levels as well as inclusion of an internal standard.
The standard is a pool of all the samples within the
experiment and therefore contains all proteins included in
the experiment. By using an internal standard, gel-to-gel
variation can be eliminated, quantification is accurate and
system variation can be separated from biological variation.
For details on experimental design, see Ettan DIGE
System User Manual, chapter 3, or DeCyder User Manual
and/or EDA User Manual, both chapter 1, or the Online Help.
The Batch Processor enables fully automated processing
of multiple gels in the DIA and BVA modules without user
The software also includes DeCyder Extended Data Analysis
Software, used for univariate and multi-variate analysis of
large and combined data sets.
Information from protein databases can be linked into the

Image Loader
Image loading
Cropping recommendations:
DeCyder software uses an Oracle Database. Therefore the
images must first be uploaded to the database before they
can be analyzed.
• Reduce the image as much as possible!
Gel name recommendations
• Ensure that all relevant spots remain inside the
Image Loader automatically groups up to three images into
one gel if the images are named with: a gel number (e.g.
Gel 01), a description of the content (e.g. dose 1 or time 3) in
parentheses and the dye used (e.g. Cy3).
For example these 3 gels will be grouped into a Gel named
Gel 01: • Gel 01 Standard Cy2.gel
• Gel 01 (Time1_Dose2) Cy3.gel
• Gel 01 (Time2_Dose2) Cy5.gel
If gel images are not named as recommended, they will not
be automatically sorted. See DeCyder User Manual,
chapter 3, or the online help for information on how to
manually group gel images.
TIP! Use short names with the most important part of the
name first.
Loading and editing images
1. Open the Image Loader module.
• All areas that do not contain usable information
should be removed.
• It is more important to ensure consistent patterns
than equal sizes
• Similar patterns facilitate correct matching.
TIP! Images can be rotated using the tools Flip and
7. Select next image and the crop tool. The most recently
used cropping rectangle is shown and can be adjusted.
8. Save one edited image at a time, or save all using Save
all. The edited images are placed in the same directory
as the original images with “edited” added to the name.
9. When the images have been imported, exit the Image
10. Check settings (Dye Chemistry etc.) and change if
required. All red texts must be edited before import.
Note: The settings can only be changed before importing
the image.
2. Select an existing project to load the images to, or
create a new project.
11. Click Import.
3. Click Add and browse for images.
12. Exit from the Image Loader.
4. Select all images to be loaded and click Open.
Note:When cropping gels for picking, the pick gel must still
contain the reference marker. To facilitate proper
matching, define an “area of interest” in the DIA
module instead. See DeCyder User Manual,
chapter 4, or the Online Help.
5. Select the images to be edited and click Edit Gel

DIA (Differential In-gel Analysis)
The DIA (Differential In-Gel Analysis) is the initial step in
DeCyder analysis and performs:
spot co-detection
spot quantification by normalization and ratio
The DIA module removes most of the system variations
Create a DIA workspace
A DIA workspace contains information from one gel.
Spot detection
1. Choose Process > Process gel images and DeCyder
spot detection algorithm 6.0.
2. For estimated number of spots: select 10,000
(overestimation) to compensate for the detection of
non-protein objects on the image, e.g. dust particles
which are subsequently excluded from the analysis.
3. Click OK.
The spots are now detected and the result is displayed.
1. Open the DIA module and select File > Create
2. Select project, all images of one gel and click Create.
Viewing - contrast/brightness settings
Adjust the contrast/brightness settings to see if there are
any image disturbances (such as Newton rings, reagent
impurities, dirty glass plates) which might affect spot
detection and matching. Especially images of preparative
gels can be very dark and may have to be adjusted.
Process gel images
The DIA module processes a set of up to 3 gel images from
a single gel. Each image is generated from samples labeled
with different dyes. The DIA algorithm detects spots on a
combined image derived from merging individual images
from an in-gel set of images. This co-detection ensures that
all spots are represented in all images.
DIA quantitates spot protein abundance for each image
and expresses these values as a ratio, thereby indicating
changes in expression levels by direct comparison of
corresponding spots.
Exclude filter
4. Choose Process > Exclude Filter and select 30,000
for volume (recommended exclusion filter for normal
quality gels, can be adjusted for different quality) and
click OK.
Do not apply the other filters. For normal quality images
other filters are not needed.
Save the workspace
5. Choose File > Save workspace.
6. Select a project to store it in or create a new project.
7. Type a workspace name and click Save.
After exclusion of non-protein objects the DIA module is
This analysis can be repeated for all gels that shall be
included in the evaluation, but we recommend using the
Batch Processor module for multiple gels, see page 11.
DeCyder 7.0, Getting Started Guide, 28-9414-49 AA
BVA (Biological Variation Analysis)
The Biological Variation Analysis (BVA):
processes multiple gel images
performs gel to gel matching of spots allowing
quantitative comparisons of protein expression across
multiple gels.
There are 4 modes in BVA with different functions:

5. Select a project to store it in or create a new project.
6. Type a workspace name and click Save.
Viewing and sorting spot maps
The spot maps included in a workspace can be viewed and
sorted in various ways.
Default sorting
New workspaces display all standard spot maps in S and M
mode by default. When moving to P mode, the spot maps
are by default sorted after experimental groups. When
returning to M mode, the sorting from P mode is kept. A
“floating” master window (i.e. it can be moved separately) is
displayed in M mode, regardless of sorting.
Custom sorting
To select different sorting, use View > Browse+Sort Gel
Images or click the icon . Customized sorting is kept
when moving between modes. For more details, see

control and red for treated, by clicking the colored dot
and selecting color.
5. Define master for matching:
Check the standard images for quality and select the
most representative image (average quality, not the
best, not the worst) and assign it as master (M).
Optional: Landmark gels
For normal gel qualities no landmarks are needed. Match
directly without setting landmarks.
General recommendations for landmark settings:
within or close to distorted region.
if possible, select spots that:
- are isolated
- are well shaped (circular)
- have medium abundance.
