The Display panel allows you to edit the parameters that display the selected image in the image view. The Display panel has individual sections for each channel available on a given acquisition. This example shows the 700 channel in red and the 800 channel in green.


Click the Features at the top left corner of the Display panel to toggle between displaying and hiding all features on the image. Features include Bands, Lanes, Wells, Spots, Annotations, and more. Select specific features to display or hide on the Show group in each Analysis tab.

Brightness and Contrast

You can adjust the display with the Brightness and Contrast sliders. Drag a slider to adjust the display.

Image Studio display panel

You can also adjust the display using curves on a histogram. Click Curves on the top of the Display panel to open the Curves tab.

You can also click the arrow (>) in the Display group on the Image tab to open a dialog and choose Curves to view the Curves for this image. Select Brightness/Contrast to view the Brightness and Contrast sliders again.


The x-axis of each panel represents the raw pixel values. Each panel has a bar graph displaying a histogram of number of pixels with each raw value. The higher the bar at a given location on the x-axis, the more pixels that contain that particular intensity value. This histogram is shaded with the color map in use for that channel. Also shown in each panel is an adjustable curve that maps raw data to displayed data.

Image Studio display panel

The adjustable curve overlaying each histogram represents how the raw data maps to the displayed data. Adjust any of the three dots on the line (Max, Min, or K Value) to optimize the displayed image.To view the numbers hover the mouse over one of the three dots in the line. The Max and Min numbers are displayed. The middle one also shows the K value, which is used to smoothly change between linear (K=0) and logarithmic (K=1) mappings of the data onto the color maps.

  • Moving the Max Point to the left is similar to increasing the Contrast value in the Odyssey software. As more of the intensity values are mapped to the brightest display values, the bands become brighter.
  • Moving the Min Point to the right shades more of the lower intensity values to lower display values, creating a visually cleaner background.
  • Increasing the K value reduces the contrast between the higher and lower intensity values, so less intense bands appear brighter while very bright bands are avoided.

Adjusting the Parameters

You can adjust each channel’s display parameters independently.

  • Image Studio 700 channel button Use the Channel label to cycle through channel views. Press once to show the single channel. Press again to show the other channels. 
  •  Image Studio 3 black icon Use the disable button to disable (gray out) the channel. This is necessary when you are adding shapes. 
  •  Image Studio color channel red icon Image Studio color channel green icon Image Studio color channel blue icon Image Studio pseudo color channel icon Use the color buttons to change the channel’s display color. 
  • Image Studio color channel gray Image Studio color channel white Use the gray scale buttons to display the channel in gray scale. This is useful for displaying the image for reports that will be published. 
  • Image Studio Zoom In iconImage Studio Zoom Out icon Use the zoom buttons to zoom in on the range of pixel values for the channel.
  • Image Studio Zoom to Fit icon Use the expand button to show the full histogram in full zoomed out view. Use the zoom in button to zoom back incrementally or the automatic button to zoom in all the way. 
  • Image Studio Pick Image icon Use the Choose Display button to select the best display from six choices. See Choose Display for more information.
  • Image Studio wizard icon Use the Adjust Display button to open a dialog to help you set the min and max points of the display mapping. See Adjust Display for more information.

The Choose Display and Adjust Display dialogs automatically open after a scan for each channel acquired. Click the arrow (>) in the Display group to open the Display Options dialog and remove the check marks to disable this feature.

Link Image Display Values

Click Link at the top of the Display panel to force all images currently in the filtered Images Table to have the same Image Display values as those applied to the display of the selected image. When the Image Display values are linked, any changes that you make to the Curves or Brightness/Contrast sliders affect all the images in the filtered view regardless of the image view mode (single image or multi-image mode).

The Link button is only enabled after a filter has been defined and applied to the Images table. It is unavailable if no filter has been applied.

The Image Display values will differ depending on the instrument and acquisition settings used. Linking the Image Display values of images from different instruments, or from the same instrument with different acquisition settings, will not provide accurate comparisons.


The Profiles tab displays a graph of Pixel Intensity vs Location for a selected shape or lane. This graph can be helpful to visually correlate band brightness with pixel intensity peaks.

Image Studio profiles tab single shape

The Profiles tab can be used to:

  1. See if a shape overlaps multiple bands
  2. Inspect the pixel intensity profile throughout a lane

Using the Profiles Tab To See If a Shape Overlaps Multiple Bands

Only one peak should appear in the shape profile if only one band is enclosed by the shape and the shape's background border.

In Figure 1, the background border width is set to 2 pixels and only one band is enclosed by Shape 1, so one peak appears in the Profiles tab. When the background border for Shape 1 is increased to 5 pixels (see Figure 2), the border can be seen to overlap another shape and an extra peak begins to appear in the Profiles tab.

Acceptable: One Profile Peak

NOT Acceptable: Two Profile Peaks

Acceptable: One Profile Peak

Image Studio profile with one peakImage Studio profile with two peaksImage Studio profile with one peak with two humps

The Profiles tab for Shape 1 contains only one peak.

An extra peak is visible above the main peak for Shape 1, because the background border width has been set to 5 instead of 2.

Although two "humps" are visible at the top of the peak, only one band is being represented. The additional peak probably comes from an area of lower optical density near the center of Shape 2.

Figure 2. The background border for Shape 1 is set to 2 pixels and does not overlap other shapes.
Figure 3. The background border for Shape 1 is set to 5 instead of 2 and now overlaps another shape.
Figure 4. The border width for Shape 2 has been set to 5, but no other bands are being overlapped.

Multiple "humps" may exist at the top of a peak . Carefully examine the Profiles tab in conjunction with the background border surrounding the shape to ensure multiple "humps" are from the same band and not different bands. For Shape 2, a less dense area inside the band is causing two peaks to appear in the Profiles tab.

Using the Profiles Tab to Inspect a Lane Profile

When a lane from a Western or MPX Western analysis is selected, the pixel intensity profile throughout the lane can be seen in the Profiles tab.

If Image Studio Lane is selected as the background subtraction method in the Define Type list Define Type icon, a line representing lane background can be displayed beneath the lane profile (see below).

Lane Background Displayed and Displayed After Background Subtraction in the Profiles tab

  • To display the lane background line, select the Display Lane Background check box and a light colored line representing the background will appear beneath the original lane profile.
  • To display the lane profile with background subtracted, select the Subtract Lane Background check box and the graph will be redrawn with lane background subtracted. The signal has already been calculated with the background subtracted, even if Subtract Lane Background has not been selected.


Use this option to assign features as concentration standards that will be used to calculate unknown concentrations of other features.

A relationship between concentration standards (added to a table) and a measured quantification value (chosen in the Concentration panel) will be determined and used to assess unknown concentrations.

To assign concentration standards and determine unknown concentrations:

  1. Click the Concentration tab at the right side of the window to display the Concentration panel. Image Studio concentration panel

  2. Click the tab at the top of the Table section to open the table with the features to be assigned as Concentration Standards. In the example below, the Plate Wells table is selected.

    Image Studio plate wells data table

  3. Click a concentration standard feature or select its row in the table.
  4. Concentration standards can only be added to one channel at a time. Check that the highlighted row is in the correct channel.

  5. Double click the Conc. Std. field in the selected row.

  6. Enter the concentration value for this feature.

    The assigned concentration standard will appear in the Concentration panel table.

    Ensure the values of the entered standards increase or decrease consistently with the quantification value chosen in the Concentration panel.

  7. Repeat steps 4 through 6 to add all of the concentration standards to the list.
  8. The calculated concentrations for the other features appear in the table in the Concentration column.
