Cell Division Viewer

  1. About Cell Division Viewer

    2. Cell Division Viewer is a tool for viewing cell division pattern data obtained by the Onami Laboratory (see     Quantitative cell division pattern analysis of C.elegans). With Cell Division Viewer, you can view images of a C.elegans embryo taken by 4D DIC microscope and 4D cell division pattern acquired from these images using image processing.

  2. Getting started

    1. Installing Java 2 Runtime Environment and Java3D API

      2. Cell Division Viewer requires Java 2 Runtime Environment and Java3D API.
      To install Java 2 Runtime Environment (Java 2 Platform, Standard Edition, v 1.4.2(J2SE)), visit       here and follow the instruction.
      To install Java3D API, visit here and follow the instruction.

    2. Increasing the memory for the Java VM

      3. Cell Division Viewer uses a large amount of memory (typically 128MB for 1 data set and 192MB for two data sets). By default, Java VM sets aside only a small amount of memory (typically 64MB). Thus, you need to increase the memory allocated to Java VM to run Cell Division Viewer.

      To Increase the memory for the Java VM:
      1. From the Windows control panel (Start->Control Panel) double click the "Java plug-in" (the Java coffee-cup icon).
      2. Select the "Advanced" tab and in "Java Runtime Parameters" specify "-Xmx128M" for 128MB or "-Xmx192M" for 192MB.
      3. Exit and restart your browser.

      Cell Division Viewer is known to run in the following environments.

  3. Quick start

    4. Cell Division Viewer has two panels. The left panel displays 4D cell division pattern of an embryo, and the right panel displays microscope images of the embryo and nuclear regions detected by image processing. Use the scroll bar at the bottom to view cell division pattern and images at different time points. Use the scroll bar at the right side to view images at different focal planes.

    1. 4D cell division pattern panel (the left panel)

      2. Drag the left mouse button to rotate the cell division pattern. Click the right mouse button to return to the original orientation. Point the mouse cursor at a nucleus and it will display the cell name of the nucleus.

    2. 4D microscope images panel (the right panel)

      3. Point the mouse cursor at a nucleus and it will display the cell name of the nucleus.
