Cell Image Set Example

Input Data

• are images of a cell collected as it grows.
• contain attributes: elapsed time, and the position and size of various features in the image.

The input file looks like:
178.18 0.0 0.0 0.0 2.71 14.36 11.65 0.0 0.0 0.0 1.42 8.49 7.07 1.35 2.87 1.52 1.03 7.21 6.18 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 /p/devise/dat/molbio/image.24

183.78 0.0 0.0 0.0 2.75 12.6 9.85 0.0 0.0 0.0 1.32 8.24 6.92 1.32 3.03 1.71 1.32 7.22 5.9 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 /p/devise/dat/molbio/image.25

Problem

Visualization

The visualization is created as follows:

1. Define the 'Feature 6 Y vs. Feature 6 X' window. This shows the location of one of the features that showed up in a large number of the images.
2. Define a window (hidden) that serves as the source for the X-Y cursor in the first window.
3. Define the 'Feature 6 length vs. Time' window. This window consists of two 'piled' views. One view (the continuous line) shows Feature 6 length vs. Time for all records in the data. The second view (the red bars) has a record link to the cursor source view, so it only shows those records that intersect the cursor in the first view.
4. The 'Images' window also consists of two piled views. One view is the source for the X cursor in the 'Feature 6 length vs. Time' window. This means that the limits on the X axis will change in response to a change in the position of the cursor in the 'Feature 6 length vs. Time' window. The view showing the small images simply displays all images that fit in the time range of this window. The view displaying the large image also has a record link to the source of the cursor in the upper left window, so only those images corresponding to the records selected by the cursor in that window will be displayed in the large size in the 'Images' window.
