This file is a three-dimensional, three-channel image recorded with a DeltaVision microscope. You can interact with the image in multiple ways:
- Zoom and Pan
- You can move the image by grabbing it with the left button on your mouse. You can zoom in and out of the image using the scroll wheel on your mouse.
- Scroll through Z and T
- Move through images in the Z axis by clicking on the vertical bar to the left of the image, or click and hold on the arrowheads. Moving through the time axis works the same way, using the horizontal bar below the image.
Note: Z and time scrolling are only supported if the original data includes three-dimensional or time-lapse data.
Please note that images in a stack are cached after you load them and can be viewed more quickly after caching.
Image Options in Full Viewer
The JCB DataViewer allows you to customize the way you view an image using the following:
- Display
- Toggle between “Normal” to view individual images in a stack, “Maximum Intensity” to view the maximum intensity projection for the complete stack, or “Split Channel” to view all channels separately and a merge view simultaneously on the same screen.
- Quality
- Toggle between “High”, “Normal” or “Low” image quality based on the extent of image compression. Lower quality images will load faster, but will not be as sharp as higher quality images.

- Line plots indicate the color intensities for specific pixels in an image across an axis. Check the box to “Enable” this functionality. You can create a horizontal or vertical line plot by toggling the drop down menu. Click on the image to position the axis. Alternatively, input a pixel position for that axis into the “X” or “Y” box and click apply. Line plots can be applied to any image in the Z or time axes by navigating using the scroll bars.
Line plots for individual colors can be created using the channel indicators described above. To remove the line plot, uncheck the “Enable” button.
- Current Image
- Displays the number of images in the z and time axes and indicates which image in the stack is currently displayed.
